垂直磁各向异性自旋阀结构中的铁磁共振
Ferromagnetic resonance in spin valve structures with p erp endicular anisotropy
摘要
Abstract
A theoretical study is presented on the magnetic-field-excited and adjusted ferromagnetic resonance in the spin valve structures with perpendicular anisotropy. Through linearizing the Landau-Lifshitz-Gilbert equation including the spin-transfer torque term, the magnetic-field-excited and adjusted ferromagnetic resonant spectra are obtained. The dependences of the resonant linewidth, resonant frequency and resonant magnetic field on the magnitude and direction of dc current density and dc magnetic field are shown. The effective damping of the system can be minimized through adjusting the magnitude and the direction of current density.关键词
