“…The smaller lattice parameters of the x = 0 powder (a = 5.3505, b = 5.6315, c = 7.6753) is consistent with this suggestion, but the difference of lattice parameters was not isotropic: a, b ≈ 0.04Å and c ≈ 0.01Å, indicating a distortion of the lattice geometry. Similar behavior was reported in yttrium-lanthanum orthoferrite, which showed an anisotropic contraction when the lanthanum ion was substituted by yttrium which has a smaller ionic radius than lanthanum [24]. The XRD pattern of the x = 2 powder showed a strong t-YBFO phase with a weak garnet phase.…”

“…Preparation of single phase yttrium orthoferrite by conventional solid state reaction of precursors oxides is difficult due to the preferred formation of secondary phases like Y 3 Fe 5 O 12 (yttrium-iron garnet) and Fe 3 O 4 [7,10,18,19]. Other synthesis routes have also been proposed including sol-gel processing of a Y-Fe mixed-metal alkoxide [6,8,20], Pechini method [11,21], microwaveassisted synthesis [15], mechanochemically assisted synthesis [22], self-propagating combustion synthesis [9,23], and inductively coupled plasma [24].…”

The thermal decomposition of Y[Fe(CN) 6 ]Á 4H 2 O has been studied in order to investigate the formation of the multi-ferroic oxide YFeO 3 . The starting material (Y[Fe(CN) 6 ]Á4H 2 O) and the decomposition products were characterized by IR spectroscopy, thermal analysis, X-ray powder diffraction (PXRD), and scanning electron microscopy. Metastable YFeO 3 with hexagonal structure, space group P6 3 /mmc, was obtained by thermal decomposition of Y[Fe(CN) 6 ]Á4H 2 O at 600 °C in air. Orthorhombic YFeO 3 was obtained by the same method at T C 800 °C in air. The crystal structure of orthorhombic YFeO 3 was refined by Rietveld analysis using PXRD data. We found that it was slightly deficient in Y 3? , which is in agreement with the small amount of Y 2 O 3 found as impurity in the sample. The formula of the orthorhombic phase is Y 0.986 FeO 3 . Keywords Y[Fe(CN) 6 ]Á4H 2 O Á YFeO 3 Á Crystal structure Á Low temperature synthesis Á Thermal decomposition J. Guimpel and Rau ´l E. Carbonio are members of the Research Career of CONICET.

“…Mechano synthesized LaFeO 3 showed a moderately high saturation magnetization, which is associated with the accumulation of several defects in the crystal structure through the mechanical treatment. The replacement of a part of La by Y 3+ cations increases the structural distortion gradually and creates a significant rise in the magnetization [11].…”

In this work, we studied the structural and magnetic properties of multiferroic La 1-x Y x FeO 3 perovskites, (x= 0.0, 0.05, 0.1, 0.15, 0.25 and 0.3) which synthesized through Sol-gel auto-combustion technique using a citric acid as a fuel. The room temperature synchrotron X-ray diffraction (XRD) analysis revealed that the all the synthesized samples consisted of the polycrystalline orthorhombic structure perovskites (space group pnma), and tolerance factor confirmed the phase stability of the prepared perovskite system. The Williamson-Hall plot based on synchrotron XRD data were employed to estimate the average particle diameter and varies from 18 nm to 27.8 nm. For a deeper insight of the crystal structure, high resolution transmission microscopy imaging (HRTEM) was performed. The estimated values of crystallite size from HRTEM and synchrotron XRD data were coincident. Many of crystallographic parameters and electron density measurements were calculated by Rietveld refinement of synchrotron XRD data. La 1-x Y x FeO 3 perovskite crystals are canted antiferromagnets with a weak ferromagnetism in room temperature. The magnetic properties were gotten through analyzing the magnetization versus temperature M(T) and M(H) hysteresis loop which characterized by a vibrating sample magnetometer (VSM). The molecular structure showed the decrease of the tilting of the octahedra with increasing Y content trying to strengthen the ferromagnetic character. Selected Area Electron Diffraction (SAED) patterns of the investigated samples exhibited spotty ring patterns, confirming the polycrystalline character. The orthoferrite La 1-x Y x FeO 3 crystals are a promising candidate for optical device applications in broad temperature range and high power system. 9 0 o 3487 http://japlive.com/index.php/jap -Journal of Advances in Physics Volume 15 (2018) ISSN: 2347 6076 beamline scientist-Elettra synchrotron-Trieste-Italy) and Lara Gigli (postdoc in MCX beamline-Elettra synchrotron-Trieste-Italy).
