| Popis: | In this work a systematic study of magnetic properties of amorphous TbxCo100-x and DyxCo100-x films is presented. In a composition range 15 < x < 40 at. %, temperature dependencies of spontaneous magnetization in a temperature interval 5 - 300 K as well as low-temperature 5 K hysteresis loops in magnetic field up to ±70 kOe have been obtained. We demonstrated, that the experimental results can be interpreted in a framework of a model considering a variable sperimagnetic cone angle of rare earth atoms up to 150. A series of Tb-Dy-Co films with a composition close to Laves phase has been obtained. We demonstrated that the variation of rare earth content with Co content fixed does not lead to a systematic lowering of magnetic hysteresis. © Published under licence by IOP Publishing Ltd.
