Exchange tensors, generalized RKKY interactions, and magnetization dynamics in heterostructures of ferromagnets and topological insulators
Christian Svingen Johnsen, Asle Sudbø
We present a comprehensive theoretical analysis of magnetic heterostructures composed of ferromagnetic (FM) layers interfaced with three-dimensional topological insulators (TIs). I…

Dynamically generated spin-interactions and nutational spin inertia in normal metal-ferromagnet heterostructures
Christian Svingen Johnsen, Asle Sudbø
We consider the spin dynamics of a normal metal-ferromagnet heterostructure, with emphasis on spin-nutation terms arising from a dynamical Ruderman-Kittel-Kasuya-Yosida (RKKY) inte…
