Summary

The crystalline lattice parameters of compounds 1-2-4 are measured as a function of calcium concentration between 0 and 0.3. The degree of a rhombic distortion of the crystalline lattice was observed to show a non-linear dependence. The effect of hydrostatic pressure on the superconducting transition temperature of compounds 1-2-4 with substitution of yttrium for calcium is studied. The critical temperature and its pressure derivative are observed to show a non-linear dependence on calcium concentration.
