Spin-Hall Nano-oscillator: a micromagnetic study

This paper studies the dynamical behavior of spin-Hall nanoscillators micromagnetically. The model parameters have been identified by reproducing recent experimental data. Our results indicate that a strongly localized mode is observed for in-plane bias fields such as in the experiments, while an asymmetric propagating mode is excited for large enough out-of plane bias field. This scenario is qualitative similar to what observed in spin-torque nanocontact oscillators. Our findings show that spin-Hall nanoscillators can find application as spin-wave emitters for magnonic applications where spin waves are used for transmission and processing information on nanoscale.
