Paper Abstract

Based on the atomic model of rare earth-Fe2 (RFe2) compounds, the magnetoelastic model of Laves phase RFe2 compounds has been proposed and it can be used to explain the strain caused by both a magnetic field and a compressive stress. The magnetic field dependence of Young's modulus under different bias stress has been founded according to magnetoelastic theory. It is found that the calculating result is in a good agreement with the experimental one for Tb0.3Dy0.7Fe2 alloy. This result indicates that the founded model can describe the relation between Young's modulus and magnetic fields under different bias stress.
