Abstract

The amorphousization of Zr65Nb35 alloy was performed. The Zr-Nb based alloys contained Al and Co elements were fabricated by arc-melting and melt-spinning methods. The superconducting property of the Zr(65-x)Nb35-xAlx (x = 0~15 at%) and Zr(65-x)Nb20Al15Cox alloys (x = 3~10 at%) was investigated by magnetic susceptibility measurements. The Zr(65-x)Nb20Al15Cox metallic glasses (x = 6~10 at%) with superconducting nanocrystalline particles dispersed in an amorphous matrix exhibited a superconductivity below about 3.5 K. The addition of Co element led drastically to the amorphousization of the superconducting Zr65Nb20Al15 alloy.
