Abstract

We investigated carbon substitution effect on boron plane of superconducting MgB $_2$ . MgB $_2$ and MgB $_{1.8}$ C $_{0.2}$ samples are synthesized under high pressure furnace. MgB $_{1.8}$ C $_{0.2}$ are characterized as AlB $_2$ -type single phase with smaller B-B distance. During the superconducting transition, two distinct onset temperatures are observed in MgB $_{1.8}$ C $_{0.2}$ .
