Spin Transport and Spin Hall Magnetoresistance
Pure spin currents represent the chargeless transport of angular momentum. They give rise to novel interface effects like the recently discovered spin Hall magnetoresistance. We investigate ...
- spin transport and the spin Hall magnetoresistance (SMR) effect in ferro-, ferri-, and antiferromagnetic materials,
- non-local effects and magnon-mediated magnetoresistance (MMR), and
- the topological Hall effect (THE) and related phenomena in materials with large spin-orbit coupling.
