Origin of the spin Seebeck effect in compensated ferrimagnets

Origin of the spin Seebeck effect in compensated ferrimagnets

Ferrimagnets possess multiple spin sub-lattices resulting in a complex magnon band structure and subtle spin transport across interfaces. Here, the authors show how the spin Seebeck effect, the thermal generation of pure spin current, may be an effective tool to study these magnetic excitations.
