Possibly Mixed Valency of Uranium in UNi5-xCux
Abstract
This paper reports the lattice constant at room temperature and the susceptibility, specific heat, electrical resistivity, and absolute Seebeck coefficient of compounds UNi5-xCux (0<=x<=5) as a function of temperature. It is suggested that the drastic change in the properties of these compounds when x, increasing from 0, comes into the range of 4 to 5 is caused by a change of the uranium ions from a U4+ to a mixed U4+-U3+ state.
