研究了磁致伸缩薄膜和非磁衬底构成的微纳悬臂梁的振动问题,根据经典弹性理论构造出其弯曲振动方程并将其与Landau-Lifshitz方程联立得到体系的动力学方程组,并得到方程组的普遍解。在此基础上考虑具体磁性薄膜结构研究了体系的铁磁共振性、弯曲振动模式的激发和在铁磁共振背景下产生的机械共振等问题,为新型微机-电器件的设计提供一些可行的途径。
The vibration of micro-nano cantilever composed of magnetostrictive film and non-magnetic substrate was studied. According to the classical elastic theory, the bending vibration equation was constructed and combined with the Landau-Lifshitz equation to obtain the dynamic equations. Get general solution to the system of equations. On the basis of this, the ferromagnetic resonance of the system, the excitation of flexural vibration mode and the mechanical resonance in the background of ferromagnetic resonance were studied in consideration of the specific magnetic thin film structure, which provided some feasible approaches for the design of the new microcomputer- .
