Abstract
A single crystal of La2CuO4 was made superconducting after treatment i n a high pressure oxygen furnace. Measurements are presented of the lo w temperature heat capacity of the insulating crystal in zero field be tween 1K and 3K, and of the superconducting crystal in fields of 0, 2 and 4 Tesla applied parallel to the ab plane between 0.2K and 3K. A li near heat capacity contribution is observed for the crystal in both th e insulating and superconducting states. This linear heat capacity con tribution is larger in the superconducting state and is insensitive to the applied magnetic field.
