Deskripsi
In this work, single-phase nanostructured NdFe<sub>1−<i>x</i></sub>Co<i><sub>x</sub></i>O<sub>3</sub> (<i>x</i> = 0, 0.1, 0.2, and 0.3) perovskite materials were obtained by annealing stoichiochemistry mixtures of their component hydroxides at 750 °C for 60 min. The partial substitution of Fe by Co in the NdFeO<sub>3</sub> crystal lattice leads to significant changes in the structural characteristics, and as a consequence, also alters both the magnetic and optical properties of the resulting perovskites. The low optical band gap (<i>E</i><sub>g</sub> = 2.06 ÷ 1.46 eV) and high coercivity (<i>H</i><sub>c</sub> = 136.76 ÷ 416.06 Oe) give Co-doped NdFeO<sub>3</sub> nanoparticles a huge advantage for application in both photocatalysis and hard magnetic devices.
