High frequency magnetic properties of ferromagnetic thin films and magnetization dynamics of coherent precession |
(a) Top view micrograph of device, wherein the key component is the Py microstrip embedded under a shorted CPW. Two methods are used to drive spin precession in the Py microstrip, (b) one is by continuous wave, (c) the other is by modulated waves excitation. (d), (e), (f) Theoretical FMR curves for different microwave magnetic field levels.[ 199 ] |
