Upper critical field Hc₂ in two-band superconductor
Palistrant, M. E.
Original · EN
It was obtained the equation for the definition of upper critical field % Hc₂ in the system with two overlapping energetic bands on the Fermi surface, which is valid for the whole temperature interval 0 ≤ T < Tc. The analytic expressions for the value Hc₂ at T Tc and T ≪ Tc cases were defined. The possibility of changing the curvature Hc₂ (T) with changing of the electrons speed ratio v₁ / v₂ on different cavities on the Fermi surface was revealed. It was obtained the qualitative accordance with experimental data for the intermetallic compound MgB₂.
