From: Time-resolved imaging of pulse-induced magnetization reversal with a microwave assist field

Switching experiments under the influence of a varying microwave excitation frequency.
(a) Time-resolved images of the reversal process in a 6 × 0.7 μm2 Py element for different excitation frequencies of the microwave current pulse. (b) Measure of the effective resonance strength (ΔMeff) as a function of applied microwave excitation frequency (fRF), from simulated magnetization mx.
