Abstract
Ferromagnetic Resonance spectra were obtained for three square-array antidot patterned Permalloy 40-nm thin films. Measurements were made with the external magnetic field pointing out-of-plane and the AC driving field in-plane. In contrast to a Permalloy sheet film, the patterned films’ FMR spectra show the existence of higher order modes of precession in additional to the uniform precession mode. The energy or frequency of the higher modes depends inversely on the spacing of the holes. We suggest the holes act as lateral boundaries allowing for the excitation of 2-D standing spin waves. A simple theoretical fitting procedure is discussed and is shown have an average deviation of only 10% from the experimental data.
