Room temperature and low-field resonant enhancement of spin Seebeck effect in partially compensated magnets

The spin Seebeck effect (SSE) converts thermally induced magnetization dynamics in magnetic materials to spin currents, but is so far an inefficient process. Here, the authors achieved resonant enhancement of the SSE voltage 700% larger than previously observed in Y3Fe5O12 by tuning the magnon lifet...
