Ca 3 Γ x Er x Co 4 O 9 + d (x ΒΌ 0, 0.05, 0.15, 0.3 and 0.5) samples were prepared using a sol-gel method followed by hot-pressing sintering technique. Powder X-ray diffraction analysis showed the single-phases of Ca 3 Γ x Er x Co 4 O 9 + d were obtained up to x ΒΌ 0.3 and the crystallinity of the sam
