Abstract

The transition temperature of NaxHfNCl (Tcmax=20.0 K) is found to be lower than that of Li0.5THFyHfNCl (TC=24.0 K). Pressure effect on Na0.3HfNCl (Tc=19.4 K) is found to be small, i.e., dTc/dP =-0.013(6) K/kbar. Powder neutron inelastic scattering on Na0.3HfNCl shows the increase in S(Q,E) at anomalous high energy, i.e., about 30 meV, in comparison with 2Δ∼8 meV with decreasing temperature from 25 to 10 K.
