Özet

The sol–gel technique was used to synthesize Er_2−xCo_xO₃ (0.0 ≤ x ≤ 0.30) mixed oxides to analyze structural and magnetic properties. The Rietveld analyses show that Er_2−xCo_xO₃ 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.
