Determining Perpendicular Magnetic Anisotropy in Fe/MgO/Fe Magnetic Tunnel Junction: A DFT-Based Spin-Orbit Torque Method

, 2023
In our JunPy package, we have combined the first-principles calculated self-consistent Hamiltonian with divide-and-conquer technique to successfully determine the magnetic anisotropy (MA) in an Fe/MgO/Fe magnetic tunnel junction (MTJ).

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...

Effect of interfacial insertion layers on the spin-orbit torque in W(O)|CoFeB heterostructures

, 2019
We report on an experimental investigation of spin-orbit torque (SOT) in W(O)∣CoFeB heterostructures where a thin insertion layer with negligible spin-orbit coupling is inserted at the W(O)∣CoFeB interface.

Nonrelativistic Spin Current Generated Unconventional Spin Hall Magnetoresistance in Altermagnetic RuO2

Advanced Science, Volume 13, Issue 31, 4 June 2026.
It is reported that the unconventional spin Hall magnetoresistance generated from nonrelativistic spin currents in RuO2 is capable of accurately detecting spin current polarization and disentangling the T̂$\hat{T}$‐odd and T̂$\hat{T}$‐even components of a spin current.
