Abstract

We discuss resistance and voltage–current characteristics of a REBa₂Cu₃O_y (REBCO, RE = rare earth) intermediate grown superconducting (iGS) joint. These characteristics are evaluated based on the current decay measurements for a REBCO closed loop. The temperature and magnetic field dependencies of the n value for the iGS joint, assessed using an empirical power-law model, are similar to those observed for REBCO tapes. The percolation model describes the voltage–current characteristics of the iGS joint more accurately. Using the critical current and n values at 10⁻⁸ V, we can approximately estimate the upper limit of the current for a low target resistance.
