Abstract

The tetragonal SrFeO_2.84 single crystal was grown by using floating zone method, and followed by resistivity and magnetization measurements with respect to temperature. Here, the magnetization data shows an antiferromagnetic ordering below 63 K, accompanied by the formation of the charge ordering. However, an anomalous insulator to metal transition occurs below 40 K in the basal plane of SrFeO_2.84 single crystal, while the resistivity along the c axis still keeps insulating. Our results reveal that, the anisotropy of resistivity in SrFeO_2.84 is caused by the magnetically driven orbital-selective Mott phase transition.
