![]() We believe that our contribution of a new, low-complexity method for the synthesis of BFO type samples, and dialogue about realising certain types of ordering in oxide perovskite systems, will assist in the further development of multiferroics for next-generation devices. There is no clear evidence for chemical ordering of Fe and Cr in the B-site of the perovskite structure and this result is rationalized by density functional theory and bond valence simulations that show a lowered energy associated with a B-site disordered structure. ![]() Through a combination of magnetometry and muon spin relaxation, it is evident that there is magnetic ordering in the BFCO phase consistent with G-type antiferromagnetism and a T N ∼ 400 K. Iron (111) oxide exists in four phases: a-Fe 2 C>3, 1-' 2, y-Fe 2 03, and e-FeCb. ![]() The rhombohedrally distorted perovskite phase was assigned to the space group R3 c by way of X-ray and neutron powder diffraction analysis. Iron oxides have extensive and significant applications in semiconductor devices, magnetooptic memories, audio-video systems, computer chips, and in memory storage devices. The procedure allowed the gram-scale production of multiferroic samples with appreciable purity and large amounts of Cr incorporation that were suitable for systematic structural investigation by neutron, X-ray, and electron diffraction in tandem with physical characterization of magnetic and ferroelectric properties. The results of the magnetic measurements suggest superparamagnetic behavior of the iron–chromium oxide nanoparticles and a weak ferromagnetic behavior.A simple, near-ambient pressure solid-state method was developed to nominally synthesize BiFe 0.5Cr 0.5O 3. Inferior electrochemical conversion activity of chromium vs iron oxide is. The organic part alone, in the absence of the inorganic component, did not develop this self-assembly. Influence of substituting iron by chromium (CrxFe2xO3 phase) is evaluated. The coated bimetallic nanoparticles proved to be thermostable up to 252 ☌ and thermotropic showing a highly organized crystalline smectic mesophase (3D plastic mesophase). The co-existence of the organic coatings and metallic core induced a special behavior that was studied by thermogravimetric analysis, differential scanning calorimetry and polarized optical microscopy. The Fourier transform infrared (FTIR) spectrum revealed the bands characteristic to metal oxides as well as to the organic components and confirmed the replacement of the acetate with long chain ligands. The bimetallic nature of the nanoparticles was emphasized by X-ray energy dispersive spectrometry (EDX) and their structure was confirmed by WAXD. The size of the obtained nanoparticles was around 11 nm, as estimated by TEM, WAXD and SAXS, which were in good agreement. The main characteristics and behaviors of the obtained nanoparticles were investigated by combined techniques. For this purpose, the substrate – bimetallic acetate – was treated with oleic acid and dodecylamine as co-ligands in trichloroacetic acid solvent at high temperature (320 ☌). The Cr2yFeyWO6 (0 < y 2) system was shown to be of the trirutile. These elements react with oxygen from water and air to form. Organic-coated iron–chromium oxide (chromite) nanoparticles have been prepared by using the thermal decomposition procedure. The iron tungstates are found to be unstable to prolonged heating at 1000 C. Stainless steel contains iron, chromium, manganese, silicon, carbon and, in many cases, significant amounts of nickel and molybdenum.
