Superconducting and electronic properties of the metallic glass system La75Si25−x M x (M=Cr, Mn, Fe, Co, Ni, Cu, B, Al, Ga, In)

Abstract

A new ternary metallic glass system, La75Si25−x M x (where M is a 3d or a IIIA element) has been prepared by melt spinning. The superconducting transition temperature,T c , is depressed by the magnetic 3d elements. For low Fe concentrations (less than ∼5 at.%) the depression is about 0.3 K/at.%. Part of the depression may be explained by a decreased density of states atE F as determined by UPS measurements. The strongest depression is associated with the magnetic pair breaking due to spin scattering. In the IIIA additions we correlateT c with the atomic radius of the additive.
