We present systematic studies of polycrystalline La12xSrxMnO3 where x is varied from 0.46 to 0.53 at 0.01 intervals. We have measured the magnetic resonance, ac susceptibility, dc magnetization, x-ray diffraction, four-probe resistivity, and optical reflectivity. The data seem to indicate that, at low T, the materials are intimate mixtures of ferromagnetic and antiferromagnetic microregions. Fo...

The evolution of the crystal structure and magnetic properties with Fe content in NdFe(x)Ga(1 - x)O(3) has been studied by magnetization, ac-susceptibility, x-ray and neutron scattering techniques for x ≥ 0.2 in order to determine the phase diagram of the series. X-ray diffraction shows that the crystallographic structure of NdFe(x)Ga(1 - x)O(3) can be described in the space group Pbnm for all ...

We developed a new method for characterizing molecular distribution in very thin liquid crystal layer (5–40 nm) evaporated onto rubbed polyimide film used by grazing-incidence X-ray diffraction (GIXD). The diffraction peaks corresponding to intermolecular correlation perpendicular to longitudinal axis of liquid crystal molecule and the clear anisotropic distribution of liquid crystal molecules ...

Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...

Sr2FeMoO6 has been extensively studied for application in spintronic devices. Through the topochemical de-intercalation of oxygen anions with metal hydride reduction, we demonstrate that the high temperature cubic phase is stabilized, at room temperature, whilst leaving the magnetic ordering intact. Synchrotron X-ray and neutron powder diffraction were used to characterize the structure and sto...

the development of nano/ultrafine bainitic structure in aisi 52100 steel was the goal of this study. for this purpose,the aisi 52100 the specimens were austenitized at 1050 °c for 60 min followed by low-temperature austemperingtreatment at different temperatures and times. the austempered samples were characterized using field emissionscanning electron microscopy (fesem), x-ray diffraction (xrd...

development of an eco-friendly, low cost and high energy density limnpo4 cathode material has attracted much attention due to its high operating voltage vs. li falling within the electrochemical stability window of conventional electrolyte solutions and offers more safety features due to the presence of a strong p-o covalent bond.synthesis of battery materials integrates the battery technology ...

a new approach for the synthesis of prussian blue nanoparticles using the cationic surfactant cetyl pyridinium chloride (cpc) as capping agent has been developed in the present work. powder x-ray diffraction, transmission electron microscopy, uv–vis absorption spectra, and ir spectroscopy were employed to characterize the product. the tem image showed that the prussian blue nanoparticles with d...
