Effect of Barium on Morphological Transition and Magnetic and Dielectric Properties in Ferrite Nanoparticles

Journal Article Dilip, R. - Journal of Superconductivity and Novel Magnetism

Barium ferrite (BaFe{sub 2}O{sub 4}) nanoparticles were synthesized by auto combustion method under different weight percentages of barium. The role of barium in the behavior of spinel ferrite property is identified from this study. XRD exhibits prominent orientation of (212) for BaFe{sub 2}O{sub 4} has confirmed especially in 20 and 30 wt% of barium. The addition of barium metal induced the specific vibration in FTIR spectra and such changes coincide well with the particle size. Further, the EDX spectrum reflects the atomic percentage of elemental presence in the samples of barium ferrite. Addition of barium on ferrite nanoparticles reduces themore »« less

Structural and Magnetic Characteristics of Ferroxplana Co{sub 2}Y Nanoferrites Synthesized via Two Chemical Routes

Journal Article Rayan, D.; EL-Gendy, M.; Kholy, Moawad; ... - Journal of Superconductivity and Novel Magnetism

Barium Y-type hexaferrite Ba{sub 2}Co{sub 2}Fe{sub 12}O{sub 22} nanopowders have been purposefully tailored using two different chemical wet methods, namely sol-gel auto-combustion (SGA) and co-precipitation (CP) routes. The impact of the pre-annealing and the annealing temperature of the formed precursors synthesized using two strategies on the structural, microstructure, and magnetic properties was investigated using x-ray diffraction (XRD), scanning electron microscopic (SEM), Fourier transform infrared spectroscopy (FT-IR), and vibrating sample magnetometer (VSM). For instance, well-defined Ba{sub 2}Co{sub 2}Fe{sub 12}O{sub 22} hexagonal plate-like particles was observed using SGA and CP routes for the precursors pre-annealed at 600 {sup ∘}C for 4 hmore »« less

Magnetic properties and magnetic states in La{sup 0.9}Sr{0.1}MnO{sub 3}.

Journal Article Korolyov, A; Arkhipov, V; Gaviko, V; ... - J. Magn. Magn. Mater.

Magnetic properties of La{sub 0.9}Sr{sub 0.1}MnO{sub 3} samples prepared by the floating-zone technique have been studied. The compound possesses different crystal structures at different temperatures T: a pseudo-cubic O''-type structure below 100 K, an orthorhombic O'-type between 100 and 320-340 K and a pseudo-cubic O-type structure above 340 K. Below {approx}145 K a ferromagnetically ordered state is observed. At low temperatures ({approx}4 K) the magnetization {sigma}, coercivity H{sub c}, differential susceptibility X{sub 0} in small fields H {approx}< H{sub c}, and the forced susceptibility X{sub {Delta}} in high fields (30-50 kOe) depend on cooling conditions.

Role of intensive milling in the processing of barium ferrite/magnetite/iron hybrid magnetic nano-composites via partial reduction of barium ferrite

Journal Article Ataie, A.; Raygan, S.; Picken, S. - Materials Characterization

In this research a mixture of barium ferrite and graphite was milled for different periods of time and then heat treated at different temperatures. The effects of milling time and heat treatment temperature on the phase composition, thermal behavior, morphology and magnetic properties of the samples have been investigated using X-ray diffraction, differential thermal analysis, high resolution transmission electron microscopy and vibrating sample magnetometer techniques, respectively. X-ray diffraction results revealed that BaFe{sub 12}O{sub 19}/Fe{sub 3}O{sub 4} nanocomposites form after a 20 h milling due to the partial reduction of BaFe{sub 12}O{sub 19}.

Synthesis and characterization of nano crystalline BaFe{sub 12}O{sub 19} powders by low temperature combustion

Journal Article Jianguo, Huang; Hanrui, Zhuang; Wenlan, Li - Materials Research Bulletin

Nano crystalline BaFe{sub 12}O{sub 19} powders have been prepared at a relatively low calcination temperature by a gel combustion technique using citric acid as a fuel/reductant and nitrates as oxidants. The effects of processing parameters, such as Ba/Fe ratio, citric acid/nitrates ratio, reaction temperature on the powder characteristics and magnetic properties of the resultant barium ferrites were investigated. By controlling the molar ratio of citric acid to metal nitrates, nano crystalline BaFe{sub 12}O{sub 19} powders with different particle sizes have been obtained. Phase attributes, microstructures and magnetic properties of the powders were characterized using X-ray diffraction analysis, X-ray line-broadening technique,more »« less
