Magnon Polarons in the Spin Seebeck Effect

27 Oct 2016 Kikkawa Takashi Shen Ka Flebus Benedetta Duine Rembert A. Uchida Ken-ichi Qiu Zhiyong Bauer Gerrit E. W. Saitoh Eiji

Sharp structures in magnetic field-dependent spin Seebeck effect (SSE) voltages of Pt/Y$_{3}$Fe$_{5}$O$_{12}$ (YIG) at low temperatures are attributed to the magnon-phonon interaction. Experimental results are well reproduced by a Boltzmann theory that includes the magnetoelastic coupling (MEC)... (read more)
