Theory of unidirectional magnetoresistance and nonlinear Hall effect

Frank Freimuth et al.

Summary: This paper studies the unidirectional magnetoresistance (UMR) and nonlinear Hall effect (NLHE) in the ferromagnetic Rashba model. By comparing two different formalisms, it is found that they lead to identical results. Additionally, this paper compares the results to those obtained in literature and finds that they converge to the same analytical formula in the limit of infinite relaxation time.

Chirality-Induced Noncollinear Magnetization and Asymmetric Domain-Wall Propagation in Hydrogenated CoPd Thin Films

Wei-Hsiang Wang et al.

Summary: Array-patterned CoPd-based heterostructures were successfully created using e-beam lithography and plasma pretreatment. The effects of subsequent hydrogenation were observed on the magnetic properties, revealing vertical and lateral antiferromagnetic coupling between the plasma-pretreated areas and the untreated areas, as well as asymmetric domain-wall propagation during magnetization reversal. These phenomena exhibit evident magnetic chirality and can be explained by coupling and interaction.

Quantifying the Dzyaloshinskii-Moriya Interaction Induced by the Bulk Magnetic Asymmetry

Qihan Zhang et al.

Summary: It is generally believed that a broken interfacial inversion symmetry in ultrathin ferromagnet/heavy metal (FM=HM) bilayers is necessary for accommodating the Dzyaloshinskii-Moriya interaction (DMI) and stabilizing chiral spin textures. In this study, the contributions of bulk magnetic asymmetry (BMA) induced by composition gradient and spin-orbit coupling (SOC) to DMI are systematically examined through experiments and theoretical calculations. The results show that both BMA and SOC play pivotal roles in achieving a sizable amplitude of DMI in certain thick films.

The effects of field history on magnetic skyrmion formation in [Pt/Co/Ir]3 multilayers

Andy T. Clark et al.

Summary: We report the formation of Ne ' el-type magnetic bubble skyrmions at room temperature in [Pt/Co/Ir]3 multilayered thin films after an in-plane magnetic field treatment. Micromagnetic simulations show that in-plane fields slightly below the saturation field are the most effective at producing skyrmions, and a small field angle away from the sample plane not only leads to improved skyrmion formation but also provides a means to select the skyrmion polarity.

Gradient-Induced Dzyaloshinskii-Moriya Interaction

Jinghua Liang et al.

Summary: In this study, we used atomistic spin calculations to investigate an intriguing type of Dzyaloshinskii-Moriya interaction (DMI) that emerges in films with composition gradient. We found that the strength and chirality of this DMI can be controlled by the composition gradient, even in disordered systems. Our study also demonstrated the DMI-induced chiral magnetic structures and field-free spin-orbit torque switching, both of which are crucial for practical device applications.

Field-Free Spin-Orbit Torque Switching Enabled by the Interlayer Dzyaloshinskii-Moriya Interaction

Wenqing He et al.

Summary: This study observes an intrinsic interlayer chiral interaction effect in a Pt/Co multilayer film and its synthetic antiferromagnetic counterpart with perpendicular magnetic anisotropy. By applying a current parallel to the eigenvector of the interlayer interaction, the perpendicular magnetization of both structures can be switched without a magnetic field, providing a new possibility for practical perpendicular SOT-MRAM and other SOT devices.

Magneto-Ionics in Annealed W/CoFeB/HfO2 Thin Films

Rohit Pachat et al.

Summary: The magneto-ionic modulation of the Dzyaloshinskii-Moriya interaction (DMI) and the perpendicular magnetic anisotropy (PMA) in W/CoFeB/HfO2 stacks is investigated by annealing at different temperatures and for varying annealing times. It is found that a large modulation of PMA and DMI is observed in the systems annealed at 390 and 350 degrees C, while no response to voltage is observed in the as-grown samples. The magnetic properties, including domain wall velocity, improve significantly with increasing annealing temperature and time, but the magneto-ionic reversibility is compromised.

Strain-tunable Dzyaloshinskii-Moriya interaction and skyrmions in two-dimensional Janus Cr2X3Y3 (X, Y = Cl, Br, I, X ≠ Y) trihalide monolayers

Zhong Shen et al.

Summary: The effect of biaxial strain on the Dzyaloshinskii-Moriya interaction (DMI), Heisenberg exchange interaction, and magnetic anisotropy energy (MAE) of Janus materials is systematically investigated using a first-principles approach. It is found that tensile strain enhances both DMI and MAE, while compressive strain induces the reversal of DMI chirality and switch of MAE from off plane to in plane. The study also reveals that DMI and MAE are mainly associated with the large spin-orbit coupling of heavy nonmagnetic halogen atoms.

Source and origin of the interfacial Dzyaloshinskii-Moriya interaction in a heavy-metal|magnetic-insulator bilayer

S. Y. Xia et al.

Summary: The strength of interfacial Dzyaloshinskii-Moriya interaction (iDMI) in Pt|TIG was quantitatively investigated by inserting thin Y3Fe5O12 and/or Cu layers between Pt and TIG. The results show that both Pt|TIG and TIG|substrate interfaces contribute to the iDMI. Pt is essential for the strong iDMI at the Pt|TIG interface, while Tm ions provide additional Tm-Fe iDMI and enhance the iDMI through spin-orbit coupling. The iDMI at the TIG|substrate interface is attributed to the lattice-mismatch-induced deformation of the electron cloud for the ferromagnetic ions.

Strain-controlled domain wall injection into nanowires for sensor applications

Giovanni Masciocchi et al.

Summary: Strain was found to increase the injection field of domain walls and the switching mechanism was strongly influenced by the strain direction. Low magnetic anisotropy facilitates the creation of domain walls, while strain-induced magnetic easy axis significantly increases the coercive field of the nucleation pad, which can be counteracted by an additional magnetic uniaxial anisotropy perpendicular to the strain-induced easy axis.

Direct Imaging of Chiral Domain Walls and Neel-Type Skyrmionium in Ferrimagnetic Alloys

Boris Seng et al.

Summary: Chiral spin structures in ferrimagnetic Ta/Ir/Fe/GdFeCo/Pt multilayers were studied using scanning electron microscopy with polarization analysis (SEMPA) as a function of temperature. GdFeCo ferrimagnet exhibited right-handed Neel-type domain wall (DW) spin textures over a large temperature range, indicating a negative Dzyaloshinskii-Moriya interaction from both the top Fe/Pt and Co/Pt interfaces. Measurements of the DW width and complementary magnetic characterization confirmed the relatively constant exchange stiffness with temperature, supporting theoretical predictions. Additionally, a pure Neel-type skyrmionium was identified through direct imaging, showing potential for application in next-generation spintronic devices due to the expected vanishing skyrmion Hall angle.

Light-induced Dzyaloshinskii-Moriya interactions in antiferromagnetic metals

Sander O. Hanslin et al.

Summary: The Dzyaloshinskii-Moriya (DM) interaction is crucial in topological spintronics, and can be induced by an ac electric field component of a laser pulse in an antiferromagnetic system with relativistic spin-orbit coupling. These induced DM interactions can be anisotropic and intense polarized laser pulses can generate both bulk-type and interfacial-type DM interactions, even when crystal symmetry would traditionally prevent one type in equilibrium. This reveals rich behaviors in periodically driven spin systems and out of equilibrium magnetic systems.
