Abstract

We have determined the distribution of the 5f-quadrupoles and detected the 5f-quadrupole order in the uranium intermetallics, uranium dipnictides and UPd₃, with ²³⁸U Mössbauer spectroscopy. We have declared that the distribution of the 5f-qaudrupoles depends on the magnetic sequence in uranium dipnictides. The distribution of the 5f-quadrupole is spherical in UBi₂, while those are oblate within c-plane in UP₂, UAs₂ and USb₂. We have observed the sudden drop of the recoil-free fraction above the transition temperature of the quadrupole order in UPd₃. The present result suggests the change of the phonon states due to the quadrupole order in this compound.
