Fig. 1: Hybrid nano-oscillator and FMR characteristics.

a Schematic of the hybrid SHNO device and power spectral density (PSD) measurement setup. b FMR frequency versus resonance field for various unpatterned thin films and heterostructures, including, for reference, Py5/Pt5 bilayers and LAFO and LFO thin films. c FMR linewidth as a function of frequency for these samples.
