Abstract
The specific heat (C) of has been measured between 0.35 and 20 K at pressures to 8.2 kbar. A very strong and nonlinear dependence on pressure is observed. In particular, the maximum in C/T, a prominent feature at zero pressure which is apparently closely related to the other unusual properties characteristic of the low-temperature behavior, disappears at even very low pressures. There is no transition to a superconducting or magnetically ordered state under pressure. Measurements at zero pressure to 50 mK show a quadratic term in C in addition to the linear term.
