• Thermodynamic activities of rare earth alloys such as La-Ce, La-Nd, and La-Gd alloys obtained with a mass-spectrometer by the present authors were summarized together with other reported values of Pr-Nd and Sm-Gd. Gibbs energy of mixing, which was calculated from the thermodynamic activity values, was compared to each other. The minimum regions of Gibbs energy of mixing in all La-Ln (Ln=Ce, Nd, Gd) alloys seem to be attained in almost equal molar compositions. The Gibbs energies of mixing and interaction parameters of the alloys were compared to each other and discussed with the Miedemas model. The difference in the electron density for elements was recognized as the important term for rare earth alloys.
