We report the superconducting properties of a new intermetallic superconductor, Cr2Re3B. Cr2Re3B has a cubic structure called the β-Mn-type structure with the space group P4132 (No. 213), and shows a superconducting transition at around Tc = 4.8 K. The magnetization curve shows a typical type-II superconducting behavior. The estimated superconducting parameters of lower and upper critical fields, coherence length ε(0), penetration depth γ (0), and Ginzburg-Landau (GL) parameter κ(0), determined using GL relations, are about Hc1(0) = 52 Oe, Hc2(0) = 100 kOe, γ(0) = 356 nm, ε (0) = 5.7 nm, and κ (0) = 62.5, respectively. The specific heat data indicates that the superconductivity in Cr 2Re3B can be described in the BCS theory. Finally, we discuss the superconducting state of Cr2Re3B using the determined parameters.
