Enhanced transport currents in Cu-sheathed MgB{sub 2} wires

Abstract

Copper-sheathed MgB{sub 2} wires, prepared by an in-situ process, were exposed to neutron radiation in order to introduce defects into the superconductor. The high level of disorder (4.6x10{sup -2} dpa) leads to a decrease of the transition temperature by more than 4 K, but to an increase of the slope of the irreversibility line, thus resulting in higher irreversibility fields at low temperatures. The transport currents are significantly enhanced at 4.2 K for fields above 2 T. (author)
