磁场可以改变具有各向异性磁化率的振动簧片的弯曲共振频率。这种效应的大小是场强的二次方。它也是磁场方向、簧片纵横比和杨氏模量、振动模式和磁化率张量的函数。这种现象可以提供磁各向异性的直接和极其灵敏的测量。
Magnetic fields may alter the flexural resonant frequencies of vibrating reeds that possess anisotropic magnetic susceptibility. The magnitude of the effect is a quadratic in the field strength. It is also a function of field orientation, the reed's aspect ratio and Young's modulus, the vibrational mode, and the magnetic susceptibility tensor. This phenomenon can provide a direct and extremely sensitive measure of magnetic anisotropy.
