Abstract:
For the classical two-phase thermodynamic theory of the Gorter-Casimir carried out a detailed analysis of the conditions of equilibrium of different phases of the magnetized superconducting system. The source expression relating mass density internal energy according to vector of magnetization and entropy change. The calculation was carried out according to the fundamental thermodynamic principle of Gibbs \',method of Lagrange multipliers subject to the General provisions of the calculus of variations. The conditions of two-phase thermodynamic equilibrium for the temperature, magnetic field and magnetic thermodynamic potential of Gibbs. The possibility of applying the obtained results for subsequent attempts the development of a modernized classical theory of super-conductivity.
