Comparison of Jc in GdBCO tape using Dc magnetisation and harmonic Ac susceptibility measurements [dataset] Open Access

We have measured the critical current density (Jc) of a sample of SuNAM HTS tape using Ac Susceptibility (ACS) and Dc Magnetisation (DCM) techniques. In DCM measurements, inhomogeneity in the applied Dc field causes a systematic underestimate of Jc. The error in DCM measurements is characterized by the penetration parameter, gamma, and grows as Jc decreases. Using a harmonic ACS analysis, we have obtained more accurate measurements of Jc as a function of applied Dc field and temperature for gamma = 1.
