Nonlinear microwave response of Nb3Sn films : A case study of granular superconductors

The universal scaling behaviour of Bon with temperature, its dependence on the thermal conductivity of the substrate, and the good agreement between the quadratic field dependence of Rs and a weakly-coupled grain model indicate heating at grain boundaries as a possible mechanism.
