ABSTRACT
A mutual inductance setup consisting of coils on opposite sides of a superconducting film is a well-known means to determine the penetration depth λ. Recently, it was shown that the same apparatus may be used to measure a nonlinear dependence of the form λ[sup 2](J)=λ[sub 0][sup 2][1+(J/J[sub 0])[sup 2]], where J is the current density and J[sub 0] characterizes the scale of nonlinear response. In this letter we calculate the nonlinear coupling between coils produced by this dependence. The calculation was done for a simplified geometry that retains the essential physics of the actual setup used in experiments, and allows quantitative evaluation of J[sub 0] within a fudge factor close to unity.
