摘要: The expression for the critical magnetic fieldHc is obtained temperatures just belowTc in two-band model. Calculation ofHc(0) niobium gives good agreement with experiment. calculated slope\((dH_c /dT)_{T_c } \) lower than experimental value. expressions forVs,Vd andV terms ofΔ0s,Δ0d andTc are derived, and values of these niobium.
