| 摘 要： | 本文详细研究了GGG(Gd3Ga5O12)单晶基片的磁转矩与其几何参量及有关物理参量的关系,提出了由转矩曲线测量石榴石磁泡薄膜单轴各向异性常数Ku和立方磁晶各向异性常数K1过程中扣除基片影响的一种方法。在此基础上利用二元回归法由实测的转矩曲线求出Ku和K1,以及Ku和K1的温度关系曲线。

| Abstract: | The dependence of the magnetic torque of single crystal GGG (Gd3Ga5O12) substrates on their geometry and some related physical parameters were studied. A method was proposed to deduce the substrate contribution in determining the uniaxial anisotropy constant Ku and magnetocrystalline one K1. Both Ku and K1 can be acquired from the magnetic torque curves by employing the two-variable regression and using computer. As example, the measured curves of Ku and K1 as a function of temperature were presented. |
