Radio-frequency methods are used to determine the variation with applied magnetic field (up to 7T) of the adiabatic susceptibility of the Van Vleck electronic paramagnet HoV0 4 , and the magnetic specific heat of the enhanced nuclear system 165HoV0 4 . The results are in good agreement with values deduced from optical measurements (Battison et al . 1977) and n.m.r. measurements (Bleaney et al . 1978).


The magnetic properties of praseodymium metal are interpreted in term s of a simple model suggested by the crystal structure where alternate layers of ions are subjected to crystal fields of face-centred cubic and hexagonal symmetry. The crystal field parameters are found by fitting the magnetic specific heat anomaly, and the variation of the susceptibility with temperature can be explained using a two-parameter molecular field model. The exchange intemaction is predominantly ferromagnetic in sign. The origin of the hyperfine specific heat is discussed, and attributed to interaction effects, though these must be larger than can be accounted for by simple theoretical estimates.
