Abstract

Micromagnetic modeling of ferromagnetic resonance (FMR) is carried out in a system comprising a cylindrical stack consisting of three ferromagnetic nanodisks, in which a helicoidal distribution of magnetic moments is realized due to magnetostatic interaction in the equilibrium state. Specificities of the rearrangement of the FMR spectrum and the spatial structure of the resonant oscillations of such a system in an external magnetic field are studied.

三个铁磁纳米盘系统中磁化的强迫振荡模型

摘要

铁磁谐振（FMR）的微磁建模是在一个系统中进行的，该系统包括一个由三个铁磁纳米盘组成的圆柱堆栈，其中由于在静平衡状态下的静磁相互作用而实现了磁矩的螺旋分布。研究了在外部磁场中这种系统的FMR频谱重排的特异性和共振振荡的空间结构。
