The monoclinic perovskite BiCo 1− x Fe x O 3 ( x ≈0.7) undergoes a second‐order structural transition from tetragonal to monoclinic, which is accompanied by a rotation of the polarization vector from the [001] to [111] directions of a pseudo cubic cell. The crystal structure, determined by electron diffraction and powder synchrotron X‐ray diffraction, was the same as that of Pb(Ti 1− x Zr x )O 3 at the morphotropic phase boundary.
