摘要

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 H_c2 generally observed in dense samples. The electronic mass anisotropy γ≈ 1.3 ±0.15 predicts some texturing in the wire. Our data on transition temperature T_c, H_c2, and both magnetic and transport critical current density J_c indicate that MgB₂ can be manufactured in a wire form using a PIT technique and required engineering J₁, can be achieved on further optimization.
