In the Mo-Si binary system. Mo(5)Si(3) crystallizes in the W(5)Si(3) (T(1) phase) structure type. However, when boron replaces silicon in this compound, a structural transition occurs from the W(5)Si(3) prototype structure to the Cr(5)B(3) prototype structure (T(2) phase) at the composition Mo(5)SiB(2). Mo(5)SiB(2) has received much attention in the literature as a candidate for structural application in high-temperature turbines, but its electronic and magnetic behavior has not been explored. In this work, we show that Mo(5)SiB(2) is a bulk superconducting material with critical temperature close to 5.8 K. The specific-heat, resistivity and magnetization measurements reveal that this material is a conventional type II BCS superconductor. (...
