Spin-orbit coupling fields in hybrid ferromagnet/semiconductor heterostructures: Effects on lateral transport and tunneling anomalous Hall effect.

 

The microscopic structure of spin-orbit fields at interfaces such as Fe/GaAs is uncovered from first principles. A symmetry based method allows obtaining the spin-orbit fields -both their magnitude and orientation- for a generic Bloch state, from the electronic band structure for any in-plane magnetization orientation. It is demonstrated that the spin-orbit fields depend not only on the electric field across the interface, but also surprisingly strongly on the Fe magnetization orientation.  The effects of the interface spin-orbit fields on the lateral transport of an Fe/GaAs slab are investigated at a phenomenological level and compared to recent experimental measurements of the magneto-crystalline anisotropy of the longitudinal resistivity.  Furthermore, it is shown that in tunnel junctions with a single ferromagnetic electrode, the interface spin-orbit fields give rise to a spin-dependent momentum filtering of the tunneling modes. As a result a tunneling anomalous Hall effect develops at the nonmagnetic counter electrode.”
