Kalta, B and Nayak, P and Nanda, KK (2012) Magnetic Field Dependence of Entropy And Specific Heat of YBa2Cu3O7-delta Superconductors. In: International Journal of Modern Physics B, 26 (2).Full text not available from this repository.
The change in thermodynamic quantities (e. g., entropy, specific heat etc.) by the application of magnetic field in the case of the high-T-c superconductor YBCO system is examined phenomenological by the Ginzburg-Landau theory of anisotropic type-II superconductors. An expression for the change in the entropy (Delta S) and change in specific heat (Delta C) in a magnetic field for any general orientation of an applied magnetic field B-a with respect to the crystallographic c-axis is obtained. The observed large reduction of specific heat anomaly just below the superconducting transition and the observed variation of entropy with magnetic field are explained quantitatively.
