Magnetization curves near showing the SOIE in optimally doped for = 6.957() (triplet A) and = 6.963() (triplet B). Here , , and denote the different oxygen ion sites in (: planar oxygen ion sites; : apical oxygen ion sites; : chain oxygen ion sites). For example, denotes a sample from batch B with in planes and in the apical and chain sites. It is evident that the planar oxygen atoms mainly contribute to the total OIE on , after [55].
