facets of the alpha(1) phase. It was observed that grain boundary phase reverse magnetization direction at lower external magnetic field compared to the SD region inside the grain. Improving grain orientation uniformity, reducing detrimental grain boundary phase volume fraction, and the branching of the alpha(1) rods, as well as their diameter, are promising routes to improve energy product of alnico.
