Magnetic attraction : The cubic perovskite BaFeO 3 (see picture, Ba blue, Fe brown, O white), which is obtained by a low‐temperature reaction using ozone as an oxidant, exhibits ferromagnetism with a fairly large moment of 3.5 μ B per Fe ion above a small critical field of approximately 0.3 T. This specific ferromagnetism is attributed to the enhancement of O→Fe charge transfer that arises from deepening of the Fe 4+ d levels.
