The Rietveld analyses show that Er2-xCoxO3 nanoparticles up to x = 0.1 have single phase, for x >= 0.2 Co3O4 phase appears. Preferential cationic distribution between the non-equivalent sites 8b and 24d is found for all samples. A systematic variation is found in the average maximum strain with composition x. The magnetic analysis showed that super-paramagnetism is the reason of S-shaped hysteresis loops and also non-zero magnetic moments. Both Mr and Ms increased with increasing concentration of Co+2.eninfo:eu-repo/semantics/closedAccessX-Ray-DiffractionPowderArticle10.1007/s10854-021-07110-y2-s2.0-85120468614
