摘要：
Thin films of Nanoperm alloys with partial substitution of iron by yttrium are the subject of investigations. The attention is fixed on the influence of yttrium substitution on structure and magnetic characteristics of the samples. The effect of film thickness is also considered. Conversion electron Mossbauer spectroscopy and magneto-optic Kerr effect were used to derive hyperfine parameters and coercive field, respectively. Coexistence of crystalline bcc-Fe phase and an amorphous one with diverse proportion was stated in most of the samples. It was found that surface and interface regions contribute to the magnetic properties of films.
