Abstract

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 lifetime via doping in $${{\rm{Lu}}}_{2}{{\rm{BiFe}}}_{4}{{\rm{GaO}}}_{12}$$ Lu2BiFe4GaO12 .

Abstract

It is demonstrated that non-resonant (os [?] op/2) wave front reversal (WFR) of spin-wave pulses (carrier frequency os) caused by pulsed parametric pumping (carrier frequency op) can be effectively used for microwave signal processing. When the spectral width Os of the signal is wider than the frequency band Op of signal amplification by pumping (Os [?] Op), the non-resonant WFR can be used for the analysis of the signal spectrum. In the opposite case (Os [?] Op) the non-resonant WFR can be used for active (with amplification) filtering of the input signal. [ABSTRACT FROM AUTHOR]
