Crystallization of Amorphous Ribbon Observed by Means of Scanning Tunneling Microscope

Surfaces of amorphous ribbon Fe70V10 B20 were observed by means of the scanning tunneling microscope before and after the annealing in vacuum.The topographic images of the air-side surfaces after annealing are similar in the x-y plane and different in the z-direction.From the scanning tunnelling microscope images some information on the crystallization of amorphous ribbons can be deduced.
