High-field magnetization study of (Nd,Dy)₂Fe₁₄B: Intrinsic properties and promising compositions

Abstract

The crystal-electric field and exchange parameters are determined for the (Nd_0.5Dy_0.5)₂Fe₁₄B compound by analyzing experimental magnetization curves obtained in high magnetic fields up to 58 T. The series (Nd_xDy_1-x)₂Fe₁₄B compounds were analyzed theoretically to achieve a temperature stability while maintaining a large maximum energy product (BH)_max. We demonstrate that computational simulations is an important tool in the materials design.
