本文介绍了一种测定单轴各向异性样品中各向异性场强的新方法。纵向MOKE与旋转磁场结合使用。由于足够大的磁场强度，可以实现类似Stoner-Wohlfarth的磁化反转过程。通过对高阶MOKE项的修正，对Fe、NiFe和Co三种不同的超薄膜进行了高精度的H-k计算。(C)1999 Elsevier Science B. V.保留所有权利。
A new method for the determination of anisotropy field strength in specimens with uniaxial anisotropy is described. Longitudinal MOKE is used in combination with a rotating magnetic field. Due to sufficient large field strength, a Stoner-Wohlfarth-like magnetisation reversal process can be realised. By correcting higher-order MOKE terms, a highly accurate calculation of H-k is demonstrated on different Fe, NiFe and Co ultra thin films. (C) 1999 Elsevier Science B.V. All rights reserved.
