Abstract :
Magnetic films of Tb31Fe69were prepared with substrate temperatures from 77K to 773k by flash evaporation and the perpendiculer anisotropy Ku has been studied with the amorphous nature. In a substrate temperature range of 77K to 623K, all films are amorphous and Ku increases up to 7×106erg/cm3with the increase of the substrate temperature. A columnar structure could not be found in this range. The annealing effect for Ku was examined together with structure analysis.
