Abstract

We report that Bi doping drives Pr2-xBixRu2O7 from an antiferromagnetic insulator (x=0) to a metallic paramagnet (x1) with a broad low T maximum in C/T. Neutron scattering reveals local low energy spin excitations (ω1meV) with a spectrum that is unaffected by heating to kBTω. We show that a continuous distribution of splittings of the non-Kramers Pr3+ ground-state doublet such as might result from various types of lattice strain can account for all the data.
