Magnetization of the KDy(WO4)2single crystal in paramagnetic phase

We report on the temperature and pressure dependences of the magnetization in the KDy(WO4)2 single crystal. The directions of magnetic axes in the crystal under study were established. It has been shown that at the point of the structural phase transition the Curie-Weiss temperature changes considerably. Under pressure of about 0.8 GPa the temperature of the structural phase transition increases nearly by a factor of two. As a result of the pressure effect the low temperature phase area is expanded.
