The phase composition, crystallographic texture, micro- and macrostresses in vacuum evaporated Co-Fe films are studied. The coercive force Hc, the field of magnetic saturation Hs and remanence ratio IR/IS are measured. Structural origin of magnetic properties are discussed. A magnetic behaviour diagram have been built in the two-dimensional field- "film thickness" and "Fe concentration" pointing out 3 different magnetic states, namely : the "thin-film", "supercritical" and "bulk" ones. The obtained results make it possible to control Co-Fe film magnetic properties in a wide range, including soft film manufacture.
