Nonlinear Studies in Magnet Garnet Films

铁磁薄膜中非线性现象的研究。高功率磁共振导致了丰富的非线性动力学过程，如规则振荡、周期倍增、不规则周期振荡、间歇性、混沌和周期窗口。解析地说，包含非线性相互作用的微观哈密顿量是适用的，由此可以得到运动方程。磁性石榴石薄膜是评价磁性材料中非线性过程的最佳系统之一。

Investigations of nonlinear phenomena in ferromagnetic thin films. Magnetic resonance at high powers leads to a rich variety of nonlinear dynamical processes such as regular oscillations, period multiplication, irregular period oscillations, intermittency, chaos, and periodic windows. Analytically, a microscopic Hamiltonian including nonlinear interactions is applicable, from which equations of motion can be obtained. Thin magnetic garnet films represent one of the best systems for the evaluation of nonlinear processes in magnetic materials.
