The effect of Co substitution for Fe in Nd3(Fe1-xCox)27.7Ti1.3Ny (x = 0.1 - 0.4) compounds on the magnetocrystalline anisotropy has been investigated. The materials were prepared by heating the parent compounds in 5 atm of high purity N2 at 743-773 K for 4h. The nitrogenation was full as confirmed by X-ray diffraction analysis (Rietveld). The anisotropy constants and the anisotropy field HA have been deduced from the magnetization curves measured on magnetically aligned powder (4-7 μm) samples by using the Sucksmith-Thompson method. At room temperature the magnetic anisotropy is uniaxial one, HA ~ 10 T and it practically doesn't change upon the Fe-substitution. At 5 K the obtained values of the anisotropy constants give evidence for the presence of easy-cone-type magnetic anisotropy. The cone angle and the anisotropy field decrease substantially upon Fe-substitution from 21.6 to 11.8 degrees and from 22.8 to 18.6 T respectively.
