当可见光被覆盖有铁磁膜的浮雕光栅衍射时，所有级衍射的强度随着磁化反转而变化。衍射强度的相对变化是在横向但通常是非镜面的克尔几何形状（反射情况，磁化垂直于衍射平面）中测量的。该效果是使用扰动近似瑞利法建模。理论计算结果与实验结果吻合较好。
When visible light is diffracted by a relief grating covered with a ferromagnetic film, the intensity diffracted in all orders varies as magnetization is reversed. The relative variation in diffracted intensity is measured in the transverse, but generally non-specular, Kerr geometry (reflection case, magnetization perpendicular to diffraction plane). The effect is modelled using a perturbation approximation to the Rayleigh method. The theoretical results are in good agreement with experiment.
