“…Neodymium-based materials are used in such applications and products as magnetic suspensions 1 , photoluminescence 2 , measurement of the grain size distribution in thin films 3 , magnetic molecules 4 , optical ring cores 5 , coloring agents for glasses 6 , and hard or soft magnets, depending on the crystal structure (a hexagonal or garnet crystal structure for hard magnets and a spinel crystal structure with an applied external magnetic field for temporary, soft magnets). When the external field decreases or disappears, the saturation magnetic value in a soft magnetic material is reduced.…”

Neodymium orthoferrite NdFeO 3 was obtained at room temperature by mechanosynthesis with a stoichiometric ratio of Nd 2 O 3 and Fe 2 O 3 powders, whereas the traditional synthesis requires a temperature of approximately 1000 °C. The crystal structure was analyzed by X-ray diffraction analysis using Cu radiation and a LynxEye XE detector, whose strong fluorescence filtering enabled a high signal intensity. The analysis indicated that the obtained crystallites were nano-sized. The particle morphology was observed by scanning electron microscopy, and the magnetic saturation was tested by vibrating sample magnetometry. The synthesis of NdFeO 3 was detected after a few hours of milling, indicating that the milling imparted mechanical energy to the system.
