Abstract

We report synthesis and characterization of binary intermetallic superconductor Mo8Ga41. Resistivity and magnetization measurements show presence of superconductivity at 9.8 K. The lower critical field (Hc1) and upper critical field (Hc2) are 150 G and 9.30 T respectively. The Ginzburg Landau coherence length (ξ) and penetration depth (λ) are estimated to be 5.95nm and 148nm respectively. As the endohedral cluster of Gallium with transition metals plays the crucial role for the presence of superconductivity in this intermetallic compound, the gallium cluster based materials can open a new avenue for novel superconductivity.
