%X A systematic study of syntheses and magnetic properties of the Nd-3 Fe29-xCrx (x=4.5, 4.7, 5.0, and 5.5) compounds has been performed. The single-phase compounds of Nd3Fe29-xCrx can be formed in the range 4.5 less than or equal to x less than or equal to 5.5. The Curie temperature Tc, the saturation magnetization M-S at 4.2 K, the anisotropy field H-A at 4.2 K and room temperature, and the intra-sublattice exchange coupling parameter j(FeFe) at 4.2 K for the Nd3Fe29-xCrx compounds decrease with increasing Cr composition from x=4.5 to 5.5, respectively. Nitrogenation and carbonation, unlike hydrogenation, result mainly in improvements of the Curie temperature, the saturation magnetization and the anisotropy field at 4.2 K and room temperature for the Nd3Fe29-xCrx compounds compared with their parent compounds.
