Transport between metals and magnetic insulators (1508.02486v2)
Published 11 Aug 2015 in cond-mat.mtrl-sci and cond-mat.mes-hall
Abstract: We derive the Onsager response matrix of fluctuation-mediated spin-collinear transport through a ferromagnetic insulator and normal metal interface driven by a temperature difference, spin accumulation, or magnetic field. We predict magnon-squeezing spin currents, magnetic field-induced cooling (magnon Peltier effect), temperature induced magnetization (thermal magnetic field) as well as universal spin Seebeck/Peltier coefficients.
