Abstract

Experimental magnetic field penetration depths δ(t, d, H) of the stable and superheated Meissner state were calculated as a function of temperature for various applied magnetic fields and various film thicknesses for two cases: (1) λ(t)/d≪κ→∞ and (2) κ≲2λ(t)/d (λ is the Ginzburg-Landau penetration depth,d is the film thickness, κ is the GL parameter). The results of the first case should be a useful tool for obtaining λ(0) of amorphous superconducting thin films.1
