Abstract:We present the results of Synchrotron XRD measurements on powdered single crystal samples of BaFe2-xRuxAs2, as a function of Ru content, and as a function of temperature, across the spin density wave transition in BaFe1.9Ru0.1As2. The Rietveld refinements reveal that with Ru substitution, while the a-axis increases, the c-axis decreases. In addition the variation of positional co-ordinates of As (zAs), the Fe-As bond length and the As-Fe-As bond angles have also been determined. In the sample with x=0.1, temperature dependent XRD measurements, indicate that the orthorhombicity shows the characteristic increase with decrease in temperature, below the magnetic transition. It is seen that the c-axis, the As-FeAs bond angles, Fe-As bond length and positional co-ordinate of the As show definite anomalies close to the structural transition. The observed anomalies in structural parameters are analysed in conjunction with geometric optimization of the structure using ab-initio electronic structure calculations.

“…The NPs, thus synthesized, were analysed by X-ray diffraction (XRD) using angle-dispersive X-ray diffraction (ADXRD) beamline (BL-12) on Indus-2 synchrotron radiation source, India. 18 The beamline is based on a Si (111)-based double-crystal monochromator. The photon beam (0.3 mm × 0.3 mm) of energy ∼11 keV was used.…”

Effect of isochronal annealing on phase transformation studies of iron oxide nanoparticles

et al. 2015

The effect of isochronal annealing on the phase transformation in iron oxide nanoparticles is reported in this work. Iron oxide nanoparticles were successfully synthesized using an ash supported technique followed by annealing for 2 h at various temperatures between 300 and 700 • C. It was observed using X-ray diffraction (XRD) and transmission electron microscopy (TEM) that as-grown samples have mixed phases of crystalline haematite (α-Fe 2 O 3 ) and a minor phase of either maghemite (γ-Fe 2 O 3 ) or magnetite (Fe 3 O 4 ). On annealing, the minor phase transforms gradually to haematite. The phase transformation is complete at annealing temperature of 442 • C as confirmed by differential scanning calorimetric (DSC) analysis. The unresolved phases in XRD were further analysed and confirmed to be maghemite from the X-ray absorption near edge structure (XANES) studies. The magnetic measurements showed that at room temperature nano-α-Fe 2 O 3 is weak ferromagnetic, and its magnetization is larger than the bulk value. The mixed phase sample shows higher value of magnetization because of the presence of ferromagnetic γ-Fe 2 O 3 phase.
