| Abstract;Experimental technique for low-temperature specific heat at high pressure has been developed. The pressures in a clamp-type cell for the specific heat measurements were determined from the superconducting transition temperatures of Tin (99.999%) at liquid helium temperatures. The linear relation of the pressures at liquid helium temperatures and applied forces at room temperature was obtained. We have measured the pressure dependence of the cooperative Jahn-Teller specific heat in the orthorhombic PrCu2 using the pressure-cell. With increasing pressure, the Jahn-Teller transition temperature increases slightly and but the specific heat peak depresses. (author abst.) |
