✦ Synopsis

Results from heat capacity measurements in the temperature range 1.8-10 K on TiHx samples with different x values are communicated. From the 3" coefficients of the electronic heat capacity the dependence of the density of states N(EF) on the x value for the cubic and the tetragonal TiHI phases is discussed, and is compared with similar results from susceptibility measurements. The estimated value for the electron-phonon interaction parameter A excludes superconductivity for TiHx. An additional lattice contribution to the heat capacity of TiHx samples with x < 1.7 was observed and seems to be related to a low-frequency anomaly in the phonon spectra.

The heat capacity of MosSnGaxS6 was measured in the temperature range from 2 K to 25K with x= 0.0, 0.18, 0.22, and 0.25. Independent of the x-value a peak appears in the phonon spectrum of all investigated compounds at low frequencies. Similar to the increase of T with the Ga concentration, a rise o
