IN SITU TEM OBSERVATION OF AMORPHOUS Nd_xFe_(1-x)THIN FILMS AND THEIR CRYSTALLIZATION

The room temperature stability and crystallization of amorphous Nd_xFe_(1-x)thin filmswith x=0.06—0.90,prepared by flash evaporation at 77 K,were investigated by X-raydiffraction and TEM observation.The amorphous Nd_xFe_(1-x)films are stable at roomtemperature when 0.19
