Thermodynamic description of a Josephson medium in a strong magnetic field
Gorbachev V. S., Senatorov A. V.
A method is proposed for generating a thermodynamic description of a ceramic high-Tc superconductor in a strong magnetic field for the case in which the length scale of the field variations is smaller than the ceramic grains. The magnetic field dependence of the transition temperature Tcj is calculated in the mean-field approximation.
