在高于400°C的温度下退火后，抛光PtMnSb的磁光克尔旋转角θK有很大的提高，而反射率R的变化很小。X射线光电子能谱分析和假设覆盖层形成的R和θK的计算表明，θK的提高不是由于覆盖层效应。结果表明，θK的提高与退火引起的表面磁各向异性的变化密切相关。
The magneto-optical Kerr rotation angle θK for polished bulk PtMnSb was found to show a great enhancement after annealing at temperatures higher than 400°C, although the change in the spectrum of reflectance R was very small. X-ray photoelectron spectroscopy analysis and the calculation of R and θK assuming the formation of overlayer revealed that the enhancement of θK was not attributable to the overlayer effect. It was found that the enhancement of θK was rather correlated with the change of magnetic anisotropy at the surface by annealing.
