Optimized Copper Distribution and Enhanced Coercivity in PrO2‐Doped Sm2Co17‐Type Magnets
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A rational design of Cu distribution is crucial for achieving optimal magnetic properties in Sm2Co17‐type magnets. In this study, nanostructured PrO2 powders were employed to induce Cu redistribution at grain boundaries while preserving the cellular microstructure. The corresponding coercivity (Hcj), remanence (Br), and maximum energy product (
