Spin caloritronic nano-oscillator
Christopher Safranski,Igor Barsukov,Han Kyu Lee,Tobias M. Schneider,Tobias M. Schneider,Alejandro Jara,Andrew Smith,Houchen Chang,Kilian Lenz,Jürgen Lindner,Yaroslav Tserkovnyak,Mingzhong Wu,Ilya Krivorotov +12 more
TL;DR: A spin torque oscillator device driven by pure spin current arising from thermal gradient across an Y3Fe5O12/Pt interface is demonstrated, paving the way towards spin caloritronic devices for microwave and magnonic applications.

TL;DR: In this article, a spin torque oscillator device driven by pure spin current arising from thermal gradient across an Y3Fe5O12/Pt interface was demonstrated. But the work paves the way towards spin caloritronic devices for microwave and magnonic applications.
Giant resonant nonlinear damping in nanoscale ferromagnets
Igor Barsukov,Han Kyu Lee,Alejandro Jara,Y.-J. Chen,A. M. Gonçalves,Chengcen Sha,Jordan A. Katine,Rodrigo Arias,Boris A. Ivanov,Ilya Krivorotov +9 more
TL;DR: In this article, a giant frequency-dependent nonlinear damping mechanism was proposed to invert the effect of spin torque on a nanomagnet leading to a surprising current-induced enhancement of damping by an antidamping torque.
