Dimensional crossover in spin Hall oscillators
Andrew Smith, Kemal Sobotkiewich, Amanatullah Khan +9
Auto-oscillations of magnetization driven by direct spin current have been previously observed in multiple quasi-zero-dimensional (0D) ferromagnetic systems such as nanomagnets and…

Coherent long-range transfer of angular momentum between magnon Kittel modes by phonons
Kyongmo An, Artem N. Litvinenko, Ryuhei Kohno +13
We report ferromagnetic resonance in the normal configuration of an electrically insulating magnetic bilayer consisting of two yttrium iron garnet (YIG) films epitaxially grown on…

Optimization of Multi-Frequency Magnonic Waveguides with Enhanced Group Velocities by Exchange Coupled Ferrimagnet/Ferromagnet Bilayers
Kyongmo An, Vinayak Bhat, Michal Mruczkiewicz +2
We report broadband spectroscopy and numerical analysis by which we explore propagating spin waves in a magnetic bilayer consisting of a 23 nm thick permalloy film deposited on 130…
