Superconductivity - Electronic characteristic measurements. Local critical current density and its distribution in large-area superconducting films Ingestion-build-143074 Changes in BS EN 12965:20191 Scope This part of IEC 61788 describes the measurements of the local critical current density (Jc) and its distribution in large area high temperature superconducting (HTS) films by an inductive method using third harmonic voltages. The most important consideration for precise measurements is to determine Jc at liquid nitrogen temperatures by an electric field criterion and obtain current voltage characteristics from its frequency dependence.
