The crystallization of amorphous films was analyzed in situ at the TEM hot stage. The changes in structure and magnetic properties of the films after annealing under vacuum were studied by X-ray diffraction and magnetic measurements. After annealing at temperature below 200℃ for 30 min, the amorphous state and the modulated structure of as-deposited samples remain basically unchanged. After annealing at temperatures≥300℃ for 30 min, the amorphous films become gradually crystallized, and completely crystallized up to 600℃ .Meanwhile,Ms of films is very sensitive to forming bcc-Fe nuclei. However the growth of these nuclei affects directly on the values of Hc.
