Typical simultaneously measured PV, , and for upsweeps (green) and downsweeps (red). The left and right insets show the orientation and a micrograph of the sample. The deviation of the traces on the left is due to a slight drift in temperature of about .

(a) PV signal at different frequencies. The black lines are fits according to Eq. (1) and the fitted FMR positions are indicated by crosses. Traces are normalized and offset. The inset shows the FMR linewidth (HWHM) and a linear fit. The value for was excluded from the fit since its lineshape is slightly distorted due to the proximity of . (b) PV for increasing temperatures for upsweeps (green) and downsweeps (red). The dashed lines are a guide to the eye and traces are offset for clarity. The inset illustrates in a projection to the plane how may turn during a hysteretic cycle.
