Abstract

The (MgB2)(1-x)COx tapes, where x = 0.0, 0.01, 0.03 and 0.05, were prepared using powder-in-tube (PIT) method. The magnetoresistance properties of the samples were investigated under applied magnetic field of 0-6 T. The T-c at 0 T was obtained to be sharp, however, became broadened by increasing the field. The activation energies, U(H), of the samples were calculated using Arrhenius law. It was found that U(H) decreased with increasing the field and Co-addition. (c) 2007 Elsevier B.V.
