N2 - We report here the physical properties of a new intermetallic superconductor Mo7Re13X(X=B,C) (Tc=8.3 K (X=B) and 8.1 K (X=C)). The crystal structure of Mo7Re13X is the β-Mn-type (cubic, space group: P4132) and the Re atoms form a tilted octahedron. The magnetization (M-H) curves show a typical type-II superconductivity; the lower critical field Hc1(0), upper critical field Hc2(0) and Ginzburg-Landau (GL) parameter value κ are, respectively, 3.0 Oe, 15.4 T and 101 for X=B and 3.1 Oe, 14.8 T and 98 for X=C. The superconducting gap versus kBTc: 2Δ/k BTc values are 4.4 for X=B and 4.2 for X=C, which implies that superconductivity in Mo7Re13X(X=B,C) can be described by an s-wave strong coupling regime.
