Spin-Hall Nano-oscillator: a micromagnetic study

摘要

This letter studies the dynamical behavior of spin-Hall nanoscillators from amicromagnetic point of view. The model parameters have been identified byreproducing recent experimental data quantitatively. Our results indicate thata strongly localized mode is observed for in-plane bias fields such as in theexperiments, while predict the excitation of an asymmetric propagating mode forlarge enough out-of plane bias field similarly to what observed in spin-torquenanocontact oscillators. Our findings show that spin-Hall nanoscillators canfind application as spin-wave emitters for magnonic applications where spinwaves are used for transmission and processing information on nanoscale.
