摘要：

Dissipation-free MgB2 superconducting wires are valuable in terms of practical applications. Herein, we have found a strong correlation between critical current density (J (c) ) and the n-value extracted from the electric field versus current density characteristic. The power-law relationship (m) between the J (c) and the n-value, , represents a critical index which is strongly dependent on operating temperatures.
