Description

We have calculated analytically the superheating field Hsub(sh) for bulk superconductors, correct to second order in kappa. We find Hsub(sh)/Hsub(c) = (kappasup(-1/2)2sup(-1/4)) x (1 + 15 √2 kappa/32), which agrees well with numerical computations for kappa < 0.5. The surface order parameter is f0(Hsub(sh)) = (1/√2) (1 - 7 √2 kappa/32), and the penetration depth is lambda(Hsub(sh))/lambda(0) = √2(1 + 3 √2 kappa/32). (orig.)

Abstract (German)

Das Ueberhitzungsfeld Hsub(sh) fuer massive Supraleiter wurde analytisch bis auf die zweite Ordnung in kappa genau berechnet. Es wurde gefunden Hsub(sh)/Hsub(c) = (kappasup(-1/2)2sup(-1/4)) x (1 + 15 √2 kappa/32), was gut mit numerischen Rechnungen fuer kappa < 0,5 uebereinstimmt. Der Oberflaechen-Ordnungsparameter ist f0(Hsub(sh)) = (1/√2) (1 - 7 √2 kappa/32) und die Eindringtiefe lambda(Hsub(sh))/lambda(0) = √2(1 + 3 √2 kappa/32). (orig.)
