摘要
The specific heat at the temperature range from 1.7 to 30 K and the dHvA effect at 0.55 K in the field up to 9.5 T have been measured for Pauli paramagnetic NiAs. The electronic specific heat coefficient is 3.0 mJ/(K-2 mel) which is in good agreement with the value estimated from the calculated density of states. It is found that the dHvA oscillation in the field along [0001] consists of four frequencies which correspond to the extremal areas in the k-space of 0.06, 0.11, 0.16 and 0.18 Angstrom(-2).
