Effect of Ni substitution in Gd-Co amorphous thin films

Substitution of Ni for Co is proposed in order to improve the properties of Gd-Co amorphous films in bubble applications. For a fixed Gd to transition metals ratio, the compensation temperature does not change appreciably and the Curie Temperature decreases from 880° K to 750° K for 50 % of Ni. The...

Summary:Substitution of Ni for Co is proposed in order to improve the properties of Gd-Co amorphous films in bubble applications. For a fixed Gd to transition metals ratio, the compensation temperature does not change appreciably and the Curie Temperature decreases from 880° K to 750° K for 50 % of Ni. The absolute saturation magnetization gives no evidence of change for Co and Ni atomic moments. For a 50 % Ni substitution, the room temperature dependence of the magnetization with the Gd concentration drops from 800 G per At % to 300 G per At %, and the magnetization is reduced by a factor of 2 for a given value of the characteristic length.
