摘要

The magnetization of dense MgB₂/Ta/Cu wires prepared by the powder-in-tube method is measured by a SQUID magnetometer. The results indicate that the critical temperature of MgB₂/Ta/Cu is around 38.4 K with a sharp transition width of 0.6 K. The MgB₂/Ta/Cu wire shows a strong flux pinning and the critical current density is higher than 10⁵ A/cm² (5 K, self-field) and 10⁴ A/cm² (20 K, 1 T). Also, the irreversibility field of the sample reaches 6.6 T at 5 K.
