Keywords: nanocomposite magnet, computer simulation, remanence enhancement, coercivity, irregular model

Magnetic properties of a model nanocomposite magnet were calculated by means of computer simulation, and the effects of the amount of the soft magnetic phase on them were studied. The numerical results show that the remanence enhanced with the increase of the soft grains, it is due to the high spontaneous magnetication of soft magnetic phases and exchange interactions. The nonuniform grains have no evident effect on the remanence of the magnet, but the coercivity decreased.
