|Title:||Microwave assisted magnetization reversal in single domain nanoelements|
|Published:||July 06, 2009|
|Abstract:||We studied the microwave assisted magnetic reversal in 65×71 nm2 elliptical Ni80Fe20 nanomagnets with a thickness of 10 nm. Hysteresis curves were measured by magneto-optical Kerr effect for a range of microwave frequencies and amplitudes. We observe a strong reduction in the coercive field when the microwave frequency coincides with the experimentally determined ferromagnetic resonance frequency in the switching region. This process occurs despite a small microwave amplitude relative to the coercive field. The experimental results were compared to numerical simulations and show good agreement.|
