抄録

The demagnetization process of exchange-coupled Sm(Fe0.8Co0.2)12/\alpha-Fe nanocomposite magnet particles with a-Fe phase coated on the sides of rectangular Sm(Fe0.8Co0.2)12 nanoparticles and the effect of Fe phase arrangement on their (BH)_{\max} are systematically investigated from micromagnetics calculations. The (BH)_{\max} of the reference model Sm(Fe0.8Co0.2)12 particles without Fe layer was 630 kJ/m3. On the other hand, the (BH)_{\max} of the nanocomposite magnet particle model, in which the four sides of the hard phase are coated with a soft phase, was found to have the highest (BH)_{\max} of 678 kJ/m3. This result may provide a guideline for designing high-performance magnet particle materials while reducing the use of rare metals.
