摘　　要：利用二次量子化方法研究了由相同面心立方结构(100)材料构成的铁磁性双层薄膜中的自旋波,重点讨论了低能量体模的波形演化情况.结果表明,面心立方晶格能量较低的体模在薄膜A-A型铁磁材料传播过程中波形完全相同,传播行为也完全相同;并且随着能量的增加,体模波长在两层铁磁薄膜材料中逐渐缩短,波速逐渐减小.Ferromagnetic bilayers with face-centered cubic(100)are studied by using a second quantization approach.The waveform evolution of low-energy bulk mode is discussed in detail.The results show that the phantom of the surface-centered cubic lattice energy is the same in the propagation process of the thin-film A-A type ferromagnetic material,and the propagation behavior is the same;and with the increase of the energy,the wavelength of the phantom is gradually shortened in the two-layer ferromagnetic thin film material,and the wave velocity is gradually reduced.
