A variational formulation and an efficient numerical method are derived for thin film critical-state problems. We use this method to solve problems for various film shapes with either the Bean or Kim current-voltage relation characterizing the superconducting material.
Using a gas diffusion technique, we have produced PbMo6Ss in the form of wires. The critical temperature of these wires is strongly dependent on the reaction conditions. Optimal conditions give a T c of 14.4 K (A Tc -~ 0.25 K). The lower limit for the critical current density at 4.2 K is 4. 104 A cm
