Pressure dependence of the low-temperature specific heat of the heavy-fermion compound CeAl3
- 1. Materials and Molecular Research Division, Lawrence Berkeley Laboratory, and Department of Chemistry, University of California, Berkeley, California 94720
Description
The specific heat (C) of CeAl3 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
