Abstract

A study is made into the effect of exchange interaction between amorphous layers of GdFeCo with ″easy plane″ type anisotropy and of DyFeCo with ″easy axis″ one on the process of two-layer film magnetization. Exchange interaction between GdFeCo and DyFeCo layers with plane and perpendicular anisotropy is investigated by way of comparison of perpendicular saturation fields (HS1) for GdFeCo monolayer film and HS3 for GdFeCo/DyFeCo two layer one. At room temperature HS3 value is 40% less than HS1) due to the change of plane orientation of magnetization in GdFeCo layer to perpendicular one because of exchange interaction.
