Superconductivity and phase diagram in a transition metal doped Zr5Ge3 compound

ORAL

Abstract

Systematic doping studies have been carried out to search for superconductivity in the transition metal doped Zr5Ge3 system at different sites. Superconductivity is only discovered with Pt doping at Ge site with Tc~2.8K and remain absent with other transition metal doping such as Y, Cr, Ir, and Pd at other different sites. Coincidental with our previous findings in the Zr5Ge3-xRux system, it appears that the induced superconductivity is not only site-selective (only at Ge site) but also dopant selective (only with Pt and Ru dopants). The bulk superconductivity in Zr5Ge3-xPtx has been investigated through resistivity, magnetization, and heat capacity measurements. The superconducting phase diagram of Pt doped Zr5Ge3-xPtx is also proposed.
