测量了NiFe/CoO双层膜中交换耦合的角依赖性，发现交换场H-E和矫顽力H-C的角依赖性和对称性不同。H-E和H-C的值是由于磁各向异性能量的单向和单轴分量，其中奇数项和偶数项分别导致H-E和H-C。提出的自由能解释了实验结果。
Angular dependence of the exchange coupling in a NiFe/CoO bilayer film has been measured, Different angular dependence and symmetry have been observed for the exchange field H-E and the coercivity H-C. The values of H-E and H-C are due to unidirectional and uniaxial components of the magnetic anisotropy energy, in which the odd and the even terms lead to H-E and H-C, respectively. The proposed free energy accounts for the experimental results.
