Abstract
We report on the transport and magnetization properties of MgB2 wires fabricated by a powder-in-tube ~PIT! technique. Temperature and magnetic-field-dependent resistivity displays a high conductivity and upper critical field Hc2 generally observed in dense samples. The electronic mass anisotropy g'1.360.15 predicts some texturing in the wire. Our data on transition temperature TC , Hc2 , and both magnetic and transport critical current density Jc indicate that MgB2 can be manufactured in a wire form using a PIT technique and required engineering Jc can be achieved on further optimization.
