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

摘要

We report on the temperature and pressure dependences of the magnetization in the KDy(WO$-4$/)$-2$/ 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.
