摘要： We report the detailed crystal structures and physical properties of Ru1-xMox alloys in the solid solution range of x= 0.1—0.9. Structure characterizations indicate that the crystal structure changes from the hcp-Mg-type, to β-CrFe-type, and then bcc-W-type. The measurements of physical properties show that the Ru1-xMox samples with x≥ 0.2 are superconductors and the superconducting transition temperature Tc as a function of Mo content exhibits a dome-like behavior.
