Project

Modeling of spin-orbitally active interfaces

Details

​Understanding the nature of spin textures and spin transport in hybrid magnetic materials is at the core of spin electronics. Whereas most of the spin-based prototype and working devices rely on the giant magnetoresistance and spin transfer torque effects, an emergent trend in materials science is the recognition of the fantastic promises of interfacial spin-orbit coupling to enable the electrical manipulation of flowing spin currents (e.g. spin Hall effect, inverse spin galvanic effect) and the control of interfacial magnetic textures (i.e. magnetic skyrmions, spin-orbit torque). Our objective is to explore the suitability of these two classes of materials to enable the electrical manipulation of the spin angular momentum, using ab initio calculations. Three aspects will be investigated using the state of the art numerical approach: (i) Spin-orbit torque (enabling the electrical manipulation of the magnetization direction), (ii) Dzyaloshinskii-Moriya interaction (resulting in chiral magnetic textures) and (iii) anisotropic damping (expected to be extremely large in these systems).
