State-resolved ultrafast charge and spin dynamics in [Co/Pd] multilayers

Loic Le Guyader et al.

Summary: Using transient absorption spectroscopy with circularly polarized x rays, we investigated the dynamics of laser-excited hole states below the Fermi level and unoccupied states above the Fermi level in ferromagnetic [Co/Pd] multilayers. The results show an instantaneous and significantly stronger demagnetization below the Fermi level, while the demagnetization above the Fermi level is delayed by 35 +/- 10 fs. This provides a direct visualization of the process of ultrafast demagnetization involving spin-flip scattering of laser-excited holes and subsequent formation of spin waves.

Spin dynamics driven by ultrafast laser-induced heating of iron garnet in high magnetic fields

I. A. Dolgikh et al.

Summary: This study reveals the heat-induced magnetization dynamics in a ferrimagnetic iron garnet at different points in the H-T phase diagram. Dynamics occur on a sub-ns timescale for non-collinear magnetizations at high magnetic field strengths. In contrast, when the field is low and magnetizations are collinear, heating alone is not sufficient to initiate dynamics, requiring an initial kick for the response of spins to thermal excitation.

Summary: We investigate the generation of local THz fields using spintronic THz emitters to improve the resolution for micrometer-sized imaging. By employing optical laser pulses as a pump, the THz field generation can be localized to the area of laser beam focusing.

Summary: Control over spin transport and spin-to-charge current conversion (S2C) in antiferromagnetic systems is studied in this work using spin pumping and THz spectroscopy techniques. The transition from the GHz to THz regime reveals a significant reduction in the characteristic propagation lengths of spin current.

Ultrafast optical control over spin and momentum in solids

S. Shallcross et al.

Summary: By employing hybrid laser pulses combining linearly and circularly polarized light, this study demonstrates the excitation of free carriers with chosen spin at an arbitrary k-vector in the Brillouin zone of WSe2. The linear terahertz component induces adiabatic intra-band evolution to link an arbitrary point k(0) to a high symmetry K point in a single pulse cycle, while the circularly polarized component induces interband transitions at one of the two inequivalent K points. The findings pave the way for preparation of excited states with arbitrary momentum and spin specificity at ultrafast timescales.

Summary: In this study, time-resolved resonant magnetic scattering experiments were used to investigate the laser induced demagnetization of Co/Pt multilayers with large perpendicular magnetic anisotropy. The results showed that after femtosecond laser irradiation, both Co and Pt components displayed a similar loss of magnetic order, but with a small delay in the Pt magnetization quenching compared to Co. Comparing the experiments with literature results suggested that the different constituents in these 3d-5d multilayers and alloys remained strongly coupled after optical excitation.

Computational analysis of transient XMCD sum rules for laser pumped systems: When do they fail?

S. Sharma et al.

Summary: In the highly non-equilibrium conditions of laser-induced spin dynamics, the validity of using x-ray magnetic circular dichroism (XMCD) sum rules to track femtosecond spin dynamics remains an open question. This study compares spin moments obtained spectroscopically with those calculated directly from density functional theory (DFT) densities and finds that for low fluence pump pulses, the two methods are in excellent agreement. However, for short and/or intense pulses with high fluence, the XMCD sum rules fail with errors exceeding 50%, likely due to the excitation of charges out of the d-band and into sp-character bands.

Atomic Scale Control of Spin Current Transmission at Interfaces

Mohamed Amine Wahada et al.

Summary: Ferromagnet/heavy metal bilayers are important for spintronic devices, where the magnetization of the ferromagnet can be controlled by spin currents generated in the heavy metal. This study demonstrates that the spin current transmission at the ferromagnet/heavy metal interface is only partial when using Ta as the heavy metal, while this effect is absent when Pt is used. This is attributed to magnetic moment reduction caused by 3d-5d hybridization effects. However, this effect can be avoided by using atomically thin interlayers. The study suggests that this is a general effect and occurs for all 5d metals with less than half-filled 5d shell.

These findings provide guidelines for scaling the power of THz radiation emitted by spintronic emitters using state-of-the-art femtosecond sources.

Laser-induced terahertz spin transport in magnetic nanostructures arises from the same force as ultrafast demagnetization

Reza Rouzegar et al.

Summary: Laser-induced terahertz spin transport and ultrafast demagnetization are two important phenomena in femtomagnetism and terahertz spintronics. This study found that the rate of ultrafast demagnetization in a ferromagnetic metal film and the time evolution of terahertz spin transport from the film to an adjacent normal-metal layer exhibit the same pattern. This suggests that both phenomena are driven by the same force determined by the state of the ferromagnet.

Summary: Spin transport is crucial for future spintronic devices. Laser-driven spin currents in F|Pt stacks are studied to identify the mechanism of spin transport, which is mediated by spin-polarized conduction electrons and/or torque between electron spins. The study reveals similar dynamics and provides an estimation of the spin-mixing conductance of the interfaces. In addition, two spin-current components with opposite directions are observed in the half-metallic ferrimagnet Fe3O4, supporting the magneto-electronic model of Fe3O4.

Probing optically induced spin currents using terahertz spin waves in noncollinear magnetic bilayers

Tom Lichtenberg et al.

Summary: This study investigates optically-induced spin currents using the excitation of THz spin-waves in noncollinear bilayer structures. The measurements show a correlation between the spin-wave phase and laser fluence, which can be explained by assuming the spin current is proportional to the time derivative of the magnetization. The results, supported by theoretical calculations and micromagnetic simulations, suggest that angular momentum transfer via the s-d interaction and ballistic interlayer transport are sufficient to explain spin-current generation and transport. Additionally, it is found that the damping-like optical spin transfer torque dominates THz spin-wave generation, indicating a shared microscopic origin for laser-induced demagnetization and spin-current generation.

Summary: Efficient terahertz generation and detection are crucial for high-performance terahertz systems. Photomixing process in photo-absorbing semiconductor material enables the generation of terahertz frequency components, which can be radiated or mixed with incoming terahertz waves in terahertz emitters and detectors. Current methods often use semiconductors with short carrier lifetimes, resulting in limited photoconductive gain and optical responsivity. Exploring alternative techniques without relying on these semiconductors is of great importance.

The role of spin-lattice coupling for ultrafast changes of the magnetic order in rare earth metals

Beatrice Andres et al.

Summary: By comparing the spin dynamics induced by femtosecond laser pulses in the surface state of the rare earth metals Gd and Tb, it is found that the spin polarization decays with different time constants in the two materials, which is attributed to distinct exchange splitting dynamics. The coupling of weak and strong 4f spin to lattice coupling in Gd and Tb respectively suggests an intimate relationship between spin polarization and 4f magnetic moment, explaining why the all optical switching phenomenon is observed in FeGd but rarely in FeTb-based compounds.

Strain-induced Anisotropic Terahertz Emission From a Fe(211)/Pt(110) Bilayer

Temperature-Dependent Terahertz Emission from Co/Mn2Au Spintronic Bilayers

Yangyang Ni et al.

Summary: The research on the THz emission behavior in cobalt (Co)/Mn2Au nanometer heterostructure revealed that the Co/Mn2Au bilayer generates sizable THz signals, while the Mn2Au/Pt bilayer does not show any THz emission. Thickness- and temperature-dependent THz emission measurements indicate a direct relation between the THz amplitude and the conductivity of the AFM Mn2Au layer.

Spin Injection Efficiency at Metallic Interfaces Probed by THz Emission Spectroscopy

Jacques Hawecker et al.

Summary: This study investigates nanometric trilayers of Co/X/Pt to explore the relationship between THz spin-to-charge conversion and traditional ferromagnetic resonance techniques. The results show that the ultrafast spin current and Gilbert damping in the trilayer are interconnected, and spin-memory-losses can be modeled via an effective Hamiltonian with Rashba fields. This work contributes to the understanding of spin-to-charge conversion processes and the potential application of magneto-circuit concepts in ultrafast spintronic devices.

Maximizing spin-orbit torque generated by the spin Hall effect of Pt

Lijun Zhu et al.

Summary: Platinum, with its giant spin Hall conductivity and compatibility with CMOS circuits, has the potential to be an outstanding provider of spin-orbit torques; however, pure clean-limit Pt with low resistivity still provides a low damping-like spin-orbit torque efficiency, limiting its practical applications; the efficiency of spin-orbit torque in Pt-based magnetic heterostructures can be significantly improved by increasing the spin Hall ratio of Pt and the spin transmissivity of the interfaces.

Optical damage limit of efficient spintronic THz emitters

Sandeep Kumar et al.

Summary: THz pulses are generated from femtosecond pulse-excited ferromagnetic/nonmagnetic spintronic heterostructures via inverse spin Hall effect. The highest possible THz signal strength from spintronic THz emitters is limited by the optical damage threshold of the corresponding heterostructures at the excitation wavelength. For the thickness-optimized spintronic heterostructure, the THz generation efficiency does not saturate with the excitation fluence even up till the damage threshold.

Generation of terahertz transients from Co2Fe0.4Mn0.6Si-Heusler-alloy/normal-metal nanobilayers excited by femtosecond optical pulses

Sarah Heidtfeld et al.

Summary: In this study, electromagnetic radiation in the terahertz frequency range was generated by optically exciting Co2Fe0.4Mn0.6Si (CFMS)/ normal-metal (NM) bilayer structures.
