Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Complex cationic‐anionic ordering in barium‐based oxygen deficient perovskites is reviewed. Considering the parent <italic>AB</italic>O₃ structure, the ordering between barium and a rare earth cation in the <italic>A</italic> site generates three classes of oxides, called double, triple and nanoscale ordered quintuple perovskites. From the ordering between a transition element (Fe, Co) and a larger cation on the <italic>B</italic> site two structural families are obtained, containing calcium and yttrium respectively. These oxides offer a vast playground for the investigation of magnetic and transport properties.</p> </abstract>
