Abstract: Advances in Magnon Caloritronics

Spin caloritronics is about the heat and spin transport in magnetic materials and devices. The spin dependent spin Seebeck effect in metallic ferromagnets and its multilayers are believed to be dominated by mass transport of conduction electrons while spin waves in magnetic insulators cause the spin Seebeck effect. Here I would like to discuss two new insights. The first one is the magnetothermal resistance in spin valves and multilayers of magnetic insulators separated by normal metal spacers, which is caused by the spin Seebeck effect [1].The second topic is the tomography of the non-equilibrium magnon distribution function by Inelastic Resonant X-Ray Scattering (RIXS) [2].
