Magnetic Prehistory in the Heat Capacity of the Low-Temperature Superconductors

Abstract:

Effect of the magnetic prehistory on the temperature dependence of the heat capacity of the superconducting Pb, La, Sn. has been studied. As soon as the external magnetic field riches the value H_ext = H_C the superconductivity is completely destroyed. The trapped flux was produced in the ring specimen after the magnetic field was turned off at T < T_C. We observed a difference of the value of the heat capacity between zero field cooled (ZFC) and field cooled (FC) states in zero magnetic field for the ring specimen. It is found that the FC heat capacity is smaller than the heat capacity both in the normal and in superconducting states.
