“…The coupling between the electric and magnetic polarizations, i.e., the magnetoelectric effect, imparts great value to such materials for practical applications due to the possibility of controlling the magnetic polarization by an electric field and vice versa [1]. We can find many examples of these materials in the perovskite-type oxides family, i.e., BiFeO 3 , BiMnO 3 , YMnO 3 , YCrO 3 , and YFeO 3 [2][3][4][5][6][7]. Yttrium orthoferrite, YFeO 3 , has a distorted perovskite structure, exhibits a weak ferromagnetic behavior, and shows an antiferromagnetic nature with a high-Ne ´el temperature T N around 640 K [6,7].…”

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.

“…To date only BiFeO 3 has been clearly identified as a ferroelectric with antiferromagnetic ordering [2][3][4] while the case of BiMnO 3 is still the subject of much debate. [5][6][7][8] BiCrO 3 is another compound for which few studies have been reported. [9] Also, the existence of a non-centrosymmetric structure together with a magnetic ordering of the Cr 3+ ion was unclear until the recent works of Belik et al [10,11] who established that BiCrO 3 exhibits a first order structural phase transition near 420 K with a step in the inverse magnetic susceptibility curves within the paramagnetic domain.…”

The structure and microstrucutre of fully-strained BiCrO3 thin films have been investigated by X-rays diffraction and transmission electron microscopy, at room temperature. Interestingly, three structural variants are simultaneously stabilized within the film. While txo of them are consistent with the existing phases in the bulk-below and above the 420 K structural transition, a different phase is identified. The existence of various structures has been attributed to the inhomogeneous distribution of local strains and oxygens resulting from a minimization of the strain-energy at the interface. These findings will open the route to a better understanding of Bi-based perovskites and metastable phases.Comment: 10 pages, 5 figures, to be published in Applied Physics Letter
