Abstract
We have succeeded for the first time in preparing single crystalline films of SrFeO3, CaFeO3, and Sr2FeCoO6, perovskites containing Fe4+, at low oxygen pressure of only 1 kPa, and the dominance of oxygen hole character in transport phenomena was indicated by the positive Hall coefficient of metallic SrFeO3.
