The heat capacity of AuTe 2 I was measured in the temperature range of 0.7 K < T < 100 K. The resulting low temperature limiting Debye temperature and electronic contribution were determined to be θ 0 = (140 ± 1.5) K and γ = (1.54 ± 0.04) mJ/mol

We report measurements of the heat capacity of the one-dimensional ionic conductor β-eucryptite (Li x Al x Si 1−2 x O 4 ) over the temperature range 1.5–320 K. The entropy and enthalpy at 298.15 K were found to be S °(298.15)=(105.34±0.7) J/mo

The anomalous metal-insulator transition in BaCo 1-x Ni x S 2-y is identified as a triggered phase transition based on strong coupling between a magnetic and a structural order parameter. In particular, we observe a second-order paramagnetic-antiferr
