Abstract

Na_xHfNCl powder samples with average sodium content x _av = 0, 0.18, 0.29, and 0.80 have been studied. The neutron powder diffraction patterns exhibit the phase separation in Na_xHfNCl system except for x = 0 and 0.29. Obtained phases are a pristine phase β-HfNCl, a superconducting phase Na_xHfNCl (T_c = 22-19 K) with narrow x-width (x = 0.28-0.29), a non-superconducting crystalline phase Na _0.9HfNCl, and a possible amorphous phase NaHfNCl.
