Quasiclassical Theory for Thermodynamic Properties of the Two-Band Superconductor MgB${}_2$ under Magnetic Fields

Masatoshi Mugikura, Hiroaki Kusunose, Yoshio Kuramoto

Consistent account is provided of strongly anisotropic properties in thermodynamics of MgB${}_2$ under magnetic field $H$ using approximate analytic solution in the quasiclassical fo…
