用穆斯堡尔谱和X射线衍射方法,研究了急冷非晶态合金薄带Fe81B13.5Si3.5C2在空气中退火时磁各向异性的变化,及其与表面结晶和整体结晶的相关性。实验表明,在空气中退火时,磁各向异性的反常变化亦与表面结晶向体结晶的发展密切相关。Changes of the magnetic anisotropy and its correlation with both surface and bulk crystallizations are studied with M?ssbauer spect scopy and X-ray diffraction for amorphous alloy Fe81B13.5Si3.5C2 annealed in the air. It is shown that abnormal changes of the magnetic anisotropy as annealing in the air is correlated with the development of surface crystallization into bulk process.
