Abstract

An analysis of new (presented below) and existing neutron diffraction experiments demonstrates that the ordered phase of UPd3 which exists between 4.5 and 7 K is described by an order parameter of B2g symmetry, and that the ordered state is triple-Q with space group P3BARm1. The order parameter describes an ordering of uranium ion quadrupoles and an associated ion displacement wave.
