Observation of the Orbital Rashba-Edelstein Magnetoresistance

Shilei Ding et al.

Summary: We report the observation of the orbital Rashba-Edelstein magnetoresistance in a Py/Cu* heterostructure, where the magnetoresistance depends on the relative angle between the induced orbital angular momentum and the magnetization. Despite the absence of heavy elements, a sizable magnetoresistance ratio was found, suggesting the presence of another mechanism in Py/Cu* structures beyond the conventional spin Hall magnetoresistance.

Crystallographic dependence of the spin Hall angle in epitaxial Pt films: Comparison of optical and electrical detection of spin-torque ferromagnetic resonance techniques

Bharat Grover et al.

Summary: In this study, the dependence of the spin Hall angle θSH was investigated in epitaxial Al2O3/Pt, MgO/Pt films using a spin-torque driven ferromagnetic resonance method. It was found that the electrical technique had limitations in accurately quantifying θSH at high current densities and could result in erroneous values, particularly for films with large inhomogeneous broadening. The study also revealed a strong dependence of θSH on the crystallographic direction.

Interface enhanced precessional damping in spintronic multilayers: A perspective

C. Swindells et al.

Summary: In the last two decades, significant progress has been made in understanding damping in multilayered thin films and spin-transport in spintronic systems. Observations in multilayered ferromagnetic/non-magnetic thin-film systems have shown an increase in damping when layered with heavy metals, leading to theoretical developments centered around the spin-pumping formalism. This paper provides a perspective on early experimental results and theoretical models explaining the enhanced damping, discusses the agreement between theory and experiment, and highlights recent observations that require further theoretical consideration, particularly related to the role of interfaces and proximity-induced magnetism in heavy metal layers.

Efficient conversion of orbital Hall current to spin current for spin-orbit torque switching

Soogil Lee et al.

Summary: The Spin Hall effect enables efficient control of magnetization, while the recent discovery of the orbital Hall effect reveals the potential for larger orbital current generation. However, a conversion process from orbital current to spin current is necessary to exert torque on a ferromagnet. By introducing rare-earth ferromagnet Gd or a Pt interfacial layer with strong spin-orbit coupling in Cr/ferromagnet structures, the orbital Hall torque can be greatly enhanced, allowing for more efficient magnetization control in spin-orbit-torque-based spintronic devices.

Determination of the spin Hall angle by the inverse spin Hall effect, device level ferromagnetic resonance, and spin torque ferromagnetic resonance: A comparison of methods

Ranen Ben-Shalom et al.

Summary: This study compares the spin torque ferromagnetic resonance (STFMR) method with two other FMR-based methods for extracting the spin Hall angle theta(SH). Despite the complexity of the interactions involved, STFMR was found to be the most robust method, providing a more accurate determination of theta(SH).

Orbital Rashba effect in a surface-oxidized Cu film

Dongwook Go et al.

Summary: Experimental observations have shown a significant enhancement of the orbital Rashba effect in a system of oxygen monolayer on top of a Cu film, leading to a strong chiral orbital texture in momentum space; Resonant hybridization between O p states and Cu d states is responsible for the emergence of the orbital Rashba effect at the interface; The application of an external electric field generates colossal orbital Hall currents, indicating a potentially significant role of the orbital torque mechanism in surface oxidized Cu/ferromagnet structures.
