ABSTRACT:
An alloy for a magnetoresistive element has an ordered phase with superstructure and consists of nickel and cobalt atoms, and the ratio of the nickel atoms to the cobalt atoms by the number of atoms is substantially within the range of 40:60 to 60:40.
A method of manufacturing an alloy for a magnetoresistive element includes the steps of preparing a substrate for a magnetoresistive element, and forming so a nickel-cobalt alloy film on the substrate at the temperature of more than 250.degree. C. that the alloy has an ordered phase with superstructure and the ratio of the nickel atoms to the cobalt atoms by the number of atoms is within the range of 40:60 to 60:40.
