Physics Division, National Center for Theoretical Sciences, Hsinchu 300, Taiwan(Dated: February 6, 2008)We investigate the non-collinear exchange coupling across the trilayer magnetic junction composedof an intermediate layer with Rashba interaction and two sandwiching ferromagnetic ones. Tocompute the mediated exchange coupling, one needs to go beyond the single-particle argumentand integrate over the contributions from the whole Fermi surface. Surprisingly, we find that thetopology of the…

CARRIER-MEDIATED EXCHANGE COUPLING AND FERMI SURFACE TOPOLOGY

We investigate the carrier-mediated exchange coupling between two ferromagnets, sandwiching an intermediate thin layer with Rashba interaction. The effective exchange coupling is obtained by

Spatial trends of noncollinear exchange coupling mediated by itinerant carriers with different Fermi surfaces

We study the exchange coupling mediated by itinerant carriers with spin-orbit interaction by both analytic and numeric approaches. The mediated exchange coupling is noncollinear and its spatial

Interlayer RKKY coupling in bulk Rashba semiconductors under topological phase transition

The bulk Rashba semiconductors BiTeX (X=I, Cl and Br) with intrinsically enhanced Rashba spin-orbit coupling provide a new platform for investigation of spintronic and magnetic phenomena in

Mirror symmetry and exchange of magnetic impurities mediated by electrons of Rashba spin–orbit interaction in a four-terminal Landauer setup

The two-dimensional paramagnetic-impurity-embedded electron gas with Rashba spin–orbit interaction in a four-terminal Landauer setup is studied. The mean-field-assisted Landauer–Keldysh formalism is
