(TU Delft QN/Blanter Group; Kavli institute of nanoscience Delft) Bauer, G.E. (TU Delft QN/Bauer Group; Tohoku University; Kavli institute of nanoscience Delft) Date 2019 Abstract We report a theory for the coherent and incoherent chiral pumping of spin waves into thin magnetic films through the dipolar coupling with a local magnetic transducer, such as a nanowire. The ferromagnetic resonance of the nanowire is broadened by the injection of unidirectional spin waves that generates a nonequilibrium magnetization in only half of the film. A temperature gradient between the local magnet and film leads to a unidirectional flow of incoherent magnons, i.e., a chiral spin Seebeck effect.
