Abstract
A mean-field model for RE-TM alloys has been developed to analyze ternary (TbFeCo) and quaternary (TbGdFeCo. TbDyFeCo) alloys of interest in thermomagnetic recording. The model is based on the localized mean-field theory and emphasizes the reduction of adjustable parameters. The experimental magnetization versus temperature curves were compared to the model predictions and good agreement was obtained in all cases. The exchange parameters and atomic moment values obtained are consistent with current understanding of these alloys.
