This study investigates the effect of cerium doping (x = 0 – 0.3) on the structure and magnetic properties of (Nd₁₋ₓCeₓ)Fe₁₁Ti alloys processed by melt-spinning and subsequent high-pressure nitriding. X-ray fluorescence confirms compositions close to the intended stoichiometry (impurities <1 wt%). X-ray diffraction reveals a predominant ThMn₁₂-type NdFe₁₁TiN phase, with minor α-Fe, and nitriding increases unit cell volume by 5–7%, confirming interstitial nitrogen incorporation. Magnetic hysteresis measurements show substantial enhancement in coercivity and remanence compared to as-cast and melt-spun states. The maximum coercivity (112.9 kA/m) is achieved at x = 0.3, while the highest saturation magnetization (137.0 A·m²/kg) occurs at x = 0.2. These results demonstrate that partial substitution of Nd with more abundant and lower-cost Ce, combined with nitriding, offers a viable pathway toward cos-effective permanent magnets with competitive performance.
