We present a systematic analysis of the iron loss behavior of grain oriented silicon steels containing different Si contents using transmission electron microscopy. When the silicon content changed in the range of 3–6.5 wt%, the iron loss showed a convex profile and the maximum iron loss was observed in 5.2 wt% silicon steel. This maximum iron loss should be ascribed to the formation of antiphase boundaries that acted as pinning centers in the magnetic domain wall.
