SOFT CO-FE FILMS - THE STRUCTURE AND MAGNETIC-PROPERTIES

The phase composition, crystallographic texture, micro- and macrostres ses in vacuum evaporated Co-Fe films are studied. The coercive force H -C, the field of magnetic saturation H-S and remanence ratio I-R/I-S a re measured. Structural origin of magnetic properties are discussed. A magnetic behaviour diagram have been built in the two-dimensional fie ld- ''film thickness'' and ''Fe concentration'' pointing out 3 differe nt magnetic states, namely: the ''thin-film'' ''supercritical'' and '' bulk'' ones. The obtained results make it possible to control Co-Fe fi lm magnetic properties in a wide range, including soft film manufactur e.
