M?SSBAUER STUDY ON CHANGES OF THE MAGNETIC ANISOTROPY AND THE CRYSTALLIZATION IN ANNEALED AMORPHOUS ALLOY Fe81B13.5Si3.5C2
非晶态合金Fe81B13.5Si3.5C2在退火过程中磁各向异性和晶化的穆斯堡尔研究

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.
