“…The appearance of iron oxide is due to the fact that a small part of the ferrite-garnet is not fully formed. This statement is also confirmed in the work [ 24 ]. The chemical composition of the studied samples was confirmed by comparing the experimental diffraction patterns with results published in publicly available databases (Match 2 and DASH 3.3.6).…”

In this study, the synthesis and magnetic properties of the rare-earth iron garnets Sm3Fe5O12, Pr3Fe5O12, and Er3Fe5O12 (in the form of powders and thin films) are reported. According to the composition, shape, and size of particles, the optimal precipitant for the synthesis of Sm3Fe5O12, Pr3Fe5O12, and Er3Fe5O12 films is an aqueous solution. The parameters for the synthesis of powders and films of the rare-earth iron garnets with micro- and nano-particles have been investigated and selected. The magnetic properties of these materials were studied; field dependencies of the magnetic moment (hysteresis loops) of nanostructured powders of iron garnets of samarium, praseodymium, and erbium in the range of +20 kOe to −20 kOe were obtained. The structural features of the Al2O3 substrate on which the films were formed are also shown.

“…Meanwhile, ceramic NdFeO3 nanoparticles typically achieve a saturation magnetization of s 0.7 M < emu/g or s 1.0 M > emu/g, as presented in [32] and [14], respectively, at the external magnetic field of 600 Oe. Another interesting feature here is that the saturation magnetization of the NdFeO3 nanoparticles was significantly higher than those of other orthoferrites of rare-earth elements RFeO3 (R = La, Y) [23][24][25][26][27]. Therefore, the NdFeO3 nanoparticles have potential applications to fabricate devices that can be applied in a high magnetic field.…”

“…Pure RFeO 3 orthoferrites (where R is La or Y), as well as RFeO 3 orthoferrites doped by Ca, Ba, Zn, and Co cations, can be produced by the following two-step approach without any surfactant: (1) the hydrolysis of cations in boiling water and (2) precipitation using appropriate agents [22][23][24][25][26][27]. This two-step process to synthesize the nanoscale NdFeO 3 has not been reported in the literature so far.…”

In this study, a nanostructured NdFeO3 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 NdFeO3 was simply synthesized by annealing a mixture of Fe (III) and Nd (III) hydroxides at 750 °C. The nanostructured NdFeO3 was obtained in spherical granules with diameters of around 30 nm. The magnetic properties of the material were a coercive force (Hc) of 136.76 Oe, a remanent magnetization (Mr) of 0.68 emu·g–1, and a saturation magnetization (Ms) of 0.79 emu·g–1.

“…During the last few decades, there has been an increased interest in the study of ferrites with various compositions due to a large number of areas of their practical application [1][2][3]. Unique structural and electromagnetic parameters allow the use of these type substances in the production of microwave ceramics, magnetically recoverable catalysts, magnetic devices, etc.…”

In this research, the formation process of nanocrystalline terbium orthoferrite (TbFeO 3) obtained via a solution combustion technique was studied using powder X-ray diffractometry, scanning electron microscopy, 57 Fe Mössbauer spectroscopy, N 2 adsorption analysis, and FTIR spectroscopy. It was shown that glycine-nitrate combustion method permits one to obtain TbFeO 3 of three different modifications: orthorhombic o-TbFeO 3 (Pbnm), hexagonal h-TbFeO 3 (P6 3 /mmc) and amorphous am-TbFeO 3. It was found that the average crystallite sizes of orthorhombic and hexagonal TbFeO 3 were 29±3 and 15±2 nm, respectively. The formation mechanism of different structural forms of terbium orthoferrite was investigated on the basis of nanopowders morphology, specific surface areas, average pore sizes, and crystallite sizes.
