Abstract: The superconductor W7Re13B has been studied by the magnetic measurements and microwave absorption. The crystal structure of W7Re13B is cubic (¯-Mn type). This compound exhibits a sharp superconducting transition at a temperature of Tc = 7:2 K. The electronic structure of W7Re13B has been studied by X-ray photoelectron spectroscopy and the band structure has been calculated by the full-potential local-orbital minimum-basis method using the scalar-relativistic mode. The main contribution to the density of states at the Fermi level is from 5d electrons of W and Re. The W and Re bands are similar and substituting W by Re does not change the total density of states.
