摘要：

Praseodymium disilicide exhibits a phase separation near 200 K into two nearly tetragonal phases. The lattice parameters and the proportion of each phase are studied as functions of the temperature by x-ray and neutron diffraction; anomalous thermal expansion is observed for one of them. Both phases order magnetically at 12 K, with different magnetic structures.
