The Investigation of the Magnetization Reversal Mechanism in the Nd-Fe-B Type Magnet, Aligned by Hot Deformation

3) belong to a group of hard magnetic materials,with excellent magnetic properties. Their unique proper-ties are determined by: high density of the nal magnet,and a signicant degree of crystallographic texture. Thedensities of the produced magnets are in range from 91%to 99.6% of the densities of powders used in productionprocess [1]. The crystallographic texture, obtained in thedeformation process, results in formation of large mag-netocrystalline anisotrop,ywhich has signicant inuenceon the magnetic parameters.In the literature there can be found many studies onthe eects of deformation conditions, such as a temper-ature, time, applied force and grain size on the mag-netic and mechanical properties of the produced magnets[15]. While, there is not much studies in which the sub-ject of discussion are reversal magnetization mechanismsoccurring in hot deformed magnets [6, 7] and the inu-ence of ariousv production conditions on the
