2D Simulation of Nd₂Fe₁₄B/α-Fe Nanocomposite Magnets with Random Grain Distributions Generated by a Monte Carlo Procedure

Figure 1

(a) The soft magnetic grains (red) are randomly distributed in the hard magnetic phase matrix (white). (b) Some sets of closed three and more soft magnetic grains (yellow) will be replaced by the one new grain with the area conservation rule. The blue parts are the parts of the soft magnetic particles hardened under the exchange coupling interactions.
