The coercivity of the Sm<sub>3</sub>(Fe,Ti)<sub>29</sub>N<sub>y</sub> nitride is controlled by the nucleation mechanism. The phenomenon of a minimum of the coercivity in the angular dependence of the coercivity is found for the Sm<sub>3</sub>(Fe,Ti)<sub>29</sub>N<sub>y</sub> nitride. The small magnetizing field required to obtain the saturation coercivity and the small interparticle interaction for the isotropic Sm<sub>3</sub>(Fe,Ti)<sub>29</sub>N<sub>y</sub> magnet imply that grains of Sm<sub>3</sub>(Fe,Ti)<sub>29</sub>N<sub>y</sub> are well isolated.
