摘要
在考虑任意磁化方向单轴和立方磁各向异性等效场的基础上,根据磁短进动方程,导出了张量磁化率X”的表达式,讨论了单晶YIG磁性薄膜中磁各向异性对铁磁共振线宽的贡献,用“各向异性线宽因子”的概念定量描述了这种贡献.理论计算与实验结果符合得很好.
Based on the consideration of the equivalent field with uniaxial and cubic magnetic anisotropy in an arbitrary magnetizing direction, the expression for tensor susceptibility is derived by the precession equation for the magnetic moment. the contribution of magnetic anisotropy to the ferromagnetic resonance linewidth in single crystal magnetic YIG film is discussed. The contribution is quantitatively described with the concept of anisotropic linewidth factor. Theoretical results are found to be in good agreement with experimental ones.
