Abstract
The crystal-electric field and exchange parameters are determined for the (Nd0.5Dy0.5)2Fe14B compound by analyzing experimental magnetization curves obtained in high magnetic fields up to 58 T. The series (NdxDy1-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.
