説明:

We discuss resistance and voltage–current characteristics of a REBCO intermediate grown superconducting (iGS) joint. The resistance and voltage–current characteristics are evaluated by the current decay measurements for a REBCO closed-loop sample. The temperature and field dependence of the n value of the iGS joint for an empirical power-law model is similar to that of REBCO tapes. The percolation model accurately describes the voltage–current characteristics of the iGS joint. Using the critical current and n values at 10^−8 V, we can approximately estimate a current for a low target resistance.
