Abstract
A model that considers combined effects of the interfacial energy and the magnetic anisotropy energy is proposed to examine development of the crystallographically aligned microstructure during annealing under a magnetic field. For ferromagnetic materials with rather large magnetic anisotropy energies, the model indicates the coarsening can take place in accordance with the magnetic anisotropy. The grain with favorite orientation survive during annealing, resulting in the alignment. The narrow distribution in the grain diameters significantly improves the alignment by coarsening. For Paramagnetic and diamagnetic materials, the coarsening is also effective to develop the aligned microstructures when low degree of the alignment can be achieved by using a magnetic field in the initial microstructure prior to the coarsening.
