Temperature-dependent band gap characteristics of Bi12SiO20 single crystals
(American Institute of Physics Inc., 2019)
Bi12SiO20 single crystals have attracted interest due to their remarkable photorefractive characteristics. Since bandgap and refractive index are related theoretically to each other, it takes much attention to investigate ...
Structural, magneto-optical properties and cation distribution of SrBixLaxYxFe12-3xO19 (0.0≤x≤0.33) hexaferrites
(Elsevier Ltd, 2016)
SrBixLaxYxFe12-3xO19 (00.0≤x≤0.33) hexaferrites were produced via sol-gel auto combustion. XRD patterns show that all the samples are single-phase M-type strontium hexaferrite (SrM). The magnetic hysteresis (σ-H) loops ...
Substitution effect of Cr 3+ on hyperfine interactions, magnetic and optical properties of Sr-hexaferrites
(Elsevier Ltd, 2018)
Chromium-substituted strontium nano-hexaferrites, SrCrxFe12-xO19 (0.0 ≤ x ≤ 1.0), were produced by the hydrothermal route. The structure, morphology, optical and magnetic properties were studied. Crystal structure, spinel ...
Synthesis and characterization of oleylamine capped MnxFe1-xFe2O4nanocomposite: Magneto-optical properties, cation distribution and hyperfine interactions
(Elsevier Ltd, 2016)
Pure Fe3O4 NPs and Oleylamin (OAm) capped MnxFe1-xFe2O4 (MnxFe1-xFe2O4@OAm) (0.2 ≤ x ≤ 1.0) nanocomposites (NCs) were synthesized by the polyol route. Lattice parameter increases with increasing Mn2+ concentration, due to ...
