Abstract
The nano-level chemical heterogeneity due to the Y segregation in RE<sub>2</sub>Fe<sub>14</sub>B phase and Ce segregation in REFe<sub>2</sub> phase enhance the hard magnetic properties of (Y,Ce)-Fe-B alloys, which offers a potential approach to improve the cost performance of free-RE magnets.
