Spin Pumping and Spin Currents in Magnetic Insulators

摘要: This chapter is devoted to pure spin current transport across ferromagnet/normal metal (F/N) interfaces. It particularly focuses on the spin-pumping process, in which magnetization dynamics excited a ferromagnet result interface, into an adjacent normal layer. Taking advantage of spin-mixing conductance concept, we quantitatively analyze experiments both metallic F/N as well insulating hybrid structures, and compare measurements based current-induced modification damping with electrical detection pumping via inverse Hall effect. We furthermore other generation schemes, namely Seebeck effect magnetoresistance, show that all three effects can be consistently understood concept.
