Popis: High‐performance R2Fe14BNx‐type magnets (R=Nd and/or Pr/Dy) were successfully prepared by sintering. The optimum magnetic properties are coercivity iHc: 680–1440 kA/m; Hc: 500–1000 kA/m; Br: 1.0–1.3 T; and (BH)m: 180–250 kJ/m3 depending on the composition and processing parameters, especially the proper sintering conditions, including nitrogen intake at 1040 to 1050 °C. The magnets thus obtained have Tc values of 335 to 370 °C depending on the nitrogen content, which should be
