Correlations of Mechanical Stresses and Magnetical Behaviour of Ion Implanted Magneto-Optical Layers
Languages of publication
Magneto-optical materials such as TbFeCo are used for data storage in a wide range. Especially the perpendicular magnetic anisotropy is necessary for high density recording. But the origin of the perpendicular magnetic anisotropy in these magneto-optical layers is not exactly known. In our experiments magneto-optical layers were implanted with heavy ions, with the aim to change the magnetic behaviour of these layers. After the implantation there is a dramatical change in the magnetical and mechanical behaviour, too.
