| 摘 要： | 研究了在倾斜磁场下感生单轴磁各向异性对静磁正向体波激发的影响，并考虑了易磁化轴垂直和平行于磁性薄膜两种情形，数值计算表明，在适当的倾斜磁场下，掺铋钇铁石榴石薄膜中的感生单轴磁各向异性能够显著降低静磁正向体波的插入损耗，增加激发带宽，因此，在静磁波器件和以静磁波为基础的磁光器件中，使用具有感生单轴各向异性的磁性薄膜可以显著提高器件的性能。

| Abstract: | This paper presented a theoretical investigation of the effects of the induced uniaxial anisotropy on excitation of magnetostatic forward volume waves under obliquely biased magnetic field. The numerical results for bismuth doped yttrium iron garnet film show that the induced uniaxial anisotropy contributes to increasing the excitation efficiency and excitation bandwidth and lowering the insertion loss under obliquely bias field. Thus, significant improvements in the device performance can be realized by using the magnetic film that possesses appropriate induced uniaxial anisotropy. |
