Spin Seebeck effect in magnetic junctions with a compensated ferrimagnet
Xin Theng Lee, Takahiro Misawa, Mamoru Matsuo +1
Compensated ferrimagnets enable ferromagnet-like spin transport without net magnetization. We study the spin Seebeck effect in a compensated ferrimagnet/normal-metal junction using…
