Two-band BCS model describes well the thermodynamics of MgB
arXiv:cond-mat/0312210
Abstract
Based on weakly-coupled anisotropic BCS theory, the dependence of energy gap and specific heat on temperature are evaluated for superconductor MgB, 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%.
