| Abstract: | Cr1-x
Fe
x
and Mn1-x
Fe
x
films were prepared at room temperature by thermal coevaporation at a deposition rate of about 25 Å/min. It was found that an amorphous phase can be obtained for Cr1-x
Fe
x
(0.25<x<0.60) films, while a metastable -Mn-type phase was observed for Mn1-x
Fe
x
(x<0.70) films. The influence of the structure on the magnetic properties has been studied. The amorphization ability of the two systems was discussed in terms of thermodynamic considerations. |
