Thermodynamics of MgB2 described by the weak-coupling two-band BCS model
Abstract
Based on weak-coupling anisotropic BCS theory, the temperature dependence of energy gap and the specific heat are evaluated for the MgB2 superconductor, and the results are compared with experimental data. We show that the weak-coupling anisotropic BCS theory describes thermodynamic experimental data with high precision, 3-6%.
