Carbon substitution effect in MgB

arXiv:cond-mat/0103169

Abstract

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