Abstract
The transition temperature of NaxHfNCl (T-c(max) =20.0 K) is found to be lo wer than that of Li0.5THFyHfNCl (T-C=24.0 K), Pressure effect on Na0.3HfNCl (T-C=19.4 K) is found to be small, i.e., dT(C)/dP =-0.013(6) K/kbar. Powde r neutron inelastic scattering on Na0.3HfNCl shows the increase in S(Q,E) a t anomalous high energy, i.e,, about 30 meV, in comparison with 2 Delta sim ilar to8 meV with decreasing temperature from 25 to 10 K.
