论文摘要
研究了由于磁场的Terahertz脉冲引起的薄膜中的脱氧化。傅立叶空间中的线性化llg方程得出了描述磁化动力学，并研究了旋转时间的演变。最后，比较了由于自旋波动力学和在相似磁系统上的最新实验观测而引起的反电磁化。因此，建立了自旋波动力学在磁化丢失中的边际作用。
Demagnetization in a thin film due to a terahertz pulse of magnetic field is investigated. Linearized LLG equation in the Fourier space to describe the magnetization dynamics is derived, and spin waves time evolution is studied. Finally, the demagnetization due to spin waves dynamics and recent experimental observations on similar magnetic system are compared. As a result of it, the marginal role of spin waves dynamics in loss of magnetization is established.
