a, c, e, Reciprocal space mapping of thin films of a, SrCoO2.5, c, SrCoO3−δ and e, phase A (HSrCoO2.5) in the (103) crystalline plane of the LSAT substrate. Å−1 represents the reciprocal space units, and Q100 and Q001 represent projected directions in the reciprocal space. b, d, f, XRD rocking curves around the peaks of b, SrCoO2.5 (008), d, SrCoO3−δ (002) and f, phase A (HSrCoO2.5) (008).
