PSD maps for a Py5/Pt5, b LAFO4/Py5/Pt5, c LAFO10/Py5/Pt5, and d LAFO20/Py5/Pt5 SHNOs. Resonance frequency as a function of external magnetic field for the device e Py5/Pt5, f LAFO4/Py5/Pt5, g LAFO10/Py5/Pt5, and h LAFO20/Py5/Pt5 obtained by FMR (brown dash-dot), ST-FMR (green dash), and PSD (blue and red solid) measurements. Dominant resonance modes are highlighted by a wider line. Notice the resonance frequency obtained from PSD has two distinctive peaks, which are associated with bulk mode and edge modes.
