电子束光刻亚微米矩形阵列的坡莫合金薄膜铁磁共振谱的研究
Ferromagnetic Resonance Study on the Permalloy Submicron Rectangular Arrays Prepared by Electron Beam Lithography
摘要
Abstract
In this paper, we report a ferromagnetic resonance study on the permalloy film of submicron-sized rectangular arrays prepared by electron beam lithography and the theoretical simulation to the non-uniform demagnetizing effect and ferromagnetic resonance data. By theoretical simulation, the magnetization, gyromagnetic ratio and g value of the sample are determined. The theoretical curves of the dependence of the resonance field on the field orientation φH fit well with the experimental data. When the steady magnetic field is applied near the film normal, a series of additional regular peaks (up to eight ) appeared in the FMR spectrum on the low field side of the main FMR peak. The resonance field of these side peaks decreases linearly with the peak number. The possible physical mechanism of these multiple peaks was discussed.关键词
