摘要
A nondestructive inductive method was developed to determine the current-voltage characteristics of superconducting films by measuring the critical current density J(c) as a function of the frequency of ac magnetic fields. In well-known inductive methods that measure the J(c) distribution of large-area films, J(c) is measured at a frequency and the electric field E induced in the superconductor is proportional to the frequency; therefore, the E versus current density relation can be determined by measuring J(c) at various frequencies. Current-voltage characteristics of YBa2Cu3O7 films measured by this method agree well with those determined by measuring magnetic-field-sweep rate dependence of magnetization.
