title: BaFeO3: a ferromagnetic iron oxide.
abstract: 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.
