A hard magnetic system of SrFe 12 O 19 nanomaterial was modified according to the composition Sr 0.95 Gd 0.05 Fe 12− x Cu with = 0.0, 0.30, and 0.60 using sol–gel technique.
Abstract In this research work Fe and Ni co-doped Tin oxide (SnO 2 ) nanoparticles have been prepared by co-precipitation method. The samples were at various combination of from 0% up to 10%. produced studied x-ray diffraction (XRD), Scanning Electron Microscopy (SEM), UV–vis Spectrophotometer, Fourier Transformation Infrared Spectroscopy (FTIR) Vibrating Sample Magnetometer (VSM). XRD study reveals the formation rutile structure undoped doped SnO with average crystallite size 1.5–10.8 nm....
This study reports the formation of Er-doped nanocrystalline cobalt ferrite with formula CoFe2-x Er x O4 (0.0 ≤ 0.10) from nontoxic metal precursors Co(NO3)2·6H2O, Fe(NO3)3·9H2O, and Er(NO3)3·5H2O through an easy economical sol-gel route in which citric acid is served as chelating agent. The as-prepared powder was annealed at 700 °C for 3 h ambient air to get required spinel structure. samples were subjected structural magnetic characterization. X-ray diffraction (XRD) data confirmed cubic...
The effect of Er content on sol-gel derived CoFe2−xErxO4, (x = 0.00, 0.01, 0.03, 0.05) nanoparticles was investigated by XRD, FTIR, SEM, Mössbauer spectroscopy, magnetic and dielectric measurements. formation cubic spinel structure the presence molecular bonding functional groups were confirmed XRD FTIR spectroscopy. average crystallite size is reduced from 61 to 18 nm with increase content. decrease in due suppression grain growth upon Er3+ occupation at octahedral site. SEM study revealed...
Cadmium oxide (CdO) and yttrium (Y) doped CdO (Y: CdO) thin films have been prepared onto glass substrate at temperature 300 °C by spray pyrolysis technique. The effects of doping on the structural, morphology, optical electrical properties were studied systematically. X-ray diffraction (XRD) study confirms that are polycrystalline in nature with cubic structure having lattice parameter 0.4658 nm. Surface topographic nano-structural analysis indicates cluster grain size porosity decreased...
The present work includes the fabrication of pure BiFeO3 and Bi0.9Y0.1Fe1−xCuxO3 (x = 0.05, 0.10, 0.15) nanoparticles by usual sol-gel route. characterization structural, morphological, optical, electrical, magnetic properties synthesized samples was achieved through x-ray diffraction spectroscopy, Raman Fourier transform infrared scanning electron microscopy, an impedance analyzer, a vibrating sample magnetometer. study confirmed presence Bi–O Fe–O bonds. patterns rhombohedral (R3c)...

Abstract A simple modification of the revised Deutsch–Märk model (RDM) [Deutsch et al., Int J Mass Spectrom 2004, 233, 13] incorporating both ionic and relativistic corrections is proposed to investigate K ‐shell ionization 30 atomic targets with numbers Z = 1–92 for incident energies up 2 GeV. We also revisit our earlier models: modified Bell (MBELL) (Haque Phys Rev 2006, 73, 012708) Kolbenstvedt (MKLV) (Uddin Eur D 37, 361), cross sections at these ultra‐relativistic energies. The results...
