摘要：

Specific heat and thermoelectric power of the Y1-xCaxTiO3 alloy system have been measured, especially near the metal-insulator (MI)-transition region around x = 0.35, in order to clarify the characteristics of a first-order transition in this region. The results are consistent with the previous electrical resistivity and magnetic susceptibility measurements in the same concentrations. This system may be interpreted as a typical example in a crossover region between a Kondo-like state and a Mott-Hubbard phase with strong correlation effect.
