Abstract
The superconducting property of Zr (1 x) Co x (x = 10-50 at.%) alloys and a Zr 55 Co 30 Al 15 bulk metallic glass fabricated using techniques of rapid solidification was investigated. The Zr 55 Co 30 Al 15 alloy crystallized by heat treatment in a vacuum atmosphere exhibited superconductivity of T c,on = 2.4 K. This was attributable to the superconducting property of a crystalline Zr-Co alloy precipitated in the Zr 55 Co 30 Al 15 alloy. The T c,on of the crystalline Zr (1 x) Co x alloy was sensitive to the Co content. The increase of Co content for the Zr (1 x) Co x alloy led to the decrease of T c,on . The Zr (1 x) Co x alloy exhibited superconductivity of a maximum T c,on = 3.9 K for the Zr 80 Co 20 alloy with superconducting nanocrystal particles embedded in the amorphous matrix.
