A harmonic analysis of a magnetic response of a second-generation high temperature superconductor YBa2Cu3Ox wire and Nb thin film in perpendicular ac field proves validity of a model of Bean’s critical-state in two-dimensional disk. We present a method of linking model and experimental susceptibility that allows contactless estimation of critical depinning current density and its temperature dependence.
