 note = {When an AC magnetic field of a suitable magnitude is applied locally to a wide surface of a superconducting film, a third harmonic voltage is induced in a pick-up coil. This measurement is used for an evaluation of the critical current density of the film. Mawatari et al. analyzed the relationship between the third harmonic voltage amplitude (V3) and the driving current amplitude for the field (I0) by using the critical state model and a simple assumption that the magnetic field is locally parallel to a flat surface. In this study, this relationship is numerically analyzed by finite element method (FEM) for a condition similar to the experiment by Mawatari et al. This result is compared with the above theoretical and experimental results. Some deviations from theory are found. However, the scaling of V3–I0 curves holds and I0 at which V3 starts to appear is proportional to the critical current density.},
