Pressure-induced superconductivity and its scaling with doping-induced superconductivity in the iron pnictide with skutterudite intermediary layers.

Abstract

Pressure-induced superconductivity is oberserved in Ca10(Pt3As8)(Fe2As2)5 by in situ high-pressure resistance and magnetic susceptibility measurements. Scaling of the pressure-induced and doping-induced superconductivity shows that the electronic phase diagrams of the pressurized and chemically doped 10–3–8 compound are similar in the moderate pressure and doping range but are disparate at higher pressure and heavy doping.
