Simple Synthesis of NdFeO<sub>3</sub> Nanoparticles By the Co-Precipitation Method Based on a Study of Thermal Behaviors of Fe (III) and Nd (III) Hydroxides
In this study, a nanostructured NdFeO<sub>3</sub> material was synthesized via a simple process of the hydrolysis of Nd (III) and Fe (III) cations in hot water with 5% NaOH as a precipitating agent. According to the results of the thermal behaviors of each hydroxide, either containing Fe...

| description | In this study, a nanostructured NdFeO<sub>3</sub> material was synthesized via a simple process of the hydrolysis of Nd (III) and Fe (III) cations in hot water with 5% NaOH as a precipitating agent. According to the results of the thermal behaviors of each hydroxide, either containing Fe (III) or Nd (III), the perovskite type of neodymium orthoferrite NdFeO<sub>3</sub> was simply synthesized by annealing a mixture of Fe (III) and Nd (III) hydroxides at 750 °C. The nanostructured NdFeO<sub>3</sub> was obtained in spherical granules with diameters of around 30 nm. The magnetic properties of the material were a coercive force (<i>H</i><sub>c</sub>) of 136.76 Oe, a remanent magnetization (<i>M</i><sub>r</sub>) of 0.68 emu·g<sup>−1</sup>, and a saturation magnetization (<i>M</i><sub>s</sub>) of 0.79 emu·g<sup>−1</sup>. |
