Single crystal growth of cubic rare earth compounds with integer quantum number of rare earths and studies of anomalous properties reflecting the quadrupole interactions

Interested in the praseodymium compounds showing the heavy-fermion-like behavior, we considered the origin of this property reflects the quadrupole moments. In this study we carried out the experiments of specific heat, thermo electric power, and magnetization of cubic rare-earth compounds with integer quantum number of rare earths. Anomalous properties of these compounds are analyzed taking into account of the coexistence of magnetic and quadrupole moments.
