Unconventional scaling and significant enhancement of the spin Seebeck effect in multilayers

Spin Seebeck effects (SSEs) have been investigated in highly crystalline magnetic multilayer [Fe3⁢O4/Pt] films. Voltage as well as power generated by the SSE were found to be significantly enhanced with increasing the number of layers . This voltage enhancement defies the simple understanding of the...
