摘要：

The structural properties and superconductivity of Mg(B1-xCx)(2) compounds were investigated by means of powder x-ray diffraction (XRD) and magnetization measurements. Powder XRD Rietveld analysis indicates that the samples crystallize in a hexagonal AlB2-type structure. The lattice parameter a decreases slightly with increasing carbon content, while c remains unchanged. The addition of carbon results in a decrease of T-C and an increase in the superconducting transition width, while the critical current density J(c) data indicate that MgB1.8C0.2 manifests comparable superconducting properties with MgB2.
