Abstract

We report a study of the depairing critical current density in the electron-doped infinite-layer Sr_1-xLa_xCuO₂ and Nd_2-xCe_xCuO_4-\delta system. In this work, many new apparatuses were set up to measure the samples. Resistance-versus-temperature transition curves measured at high pulsed current densities show the classic proportionality between the transition-temperature shift and the two-thirds power of the applied current. The measurement provides an assessment of the superfluid density in the system, and a secondary route for obtaining the penetration depth purely through a transport measurements.
