Scaling of extended defects in nano-sized Brownmillerite CaFeO2.5

We investigated the formation of extended defects in CaFeO2.5, predominantly appearing as antiphase boundaries (APBs), as a function of the synthesis method and temperature. While CaFeO2.5 is known to adopt an ordered oxygen defect structure showing long range order of the (FeO4)∞ chains in its bulk...
