The influence of the heat treatment on the structural and magnetic properties of nanoparticle La0.7Ca0.3MnO3 prepared by glycine-nitrate method
(Journal of Alloys and Compounds, 2010)
The influence of the heat treatment on the structural and magnetic properties of the nanoparticle La0.7Ca0.3MnO3 compound has been studied. The starting single-phase sample was prepared by the glycine nitrate method without ...
Room temperature ferromagnetism in Cu2+ doped TiO2 nanocrystals: The impact of their size, shape and dopant concentration
(Elsevier, 2016)
Cu2+ doped TiO2 nanocrystals were synthesized using dispersions of titania nanotubes in the presence of Cu2+ ions as a precursors. The morphologies of nanotubular titania precursors and resulted Cu2+ doped TiO2 nanocrystals ...
Analysis of the structures of the Cu(I) and Cu(II) complexes with 3-acetylpyridine and thiocyanate
(Polyhedron, 2014)
3-Acetylpyridine thiosemicarbazone hydrochloride was synthesized and structurally characterized. Complexes of Cu(II) with this ligand could not be obtained by direct synthesis. By synthesis in situ mixing Cu(BF4)(2)center ...
Temperature induced evolution of structure/microstructure parameters and their correlations with electric/magnetic properties of nanocrystalline Nickel ferrite
(Ceramics International, 2014)
Nickel ferrite nanoparticles were annealed in order to find dependence of electric/magnetic properties on crystallite size. The following correlations of crystallite size with physical parameters were found: (a) lattice ...
Synthesis, morphology and microstructure of pomegranate-like hematite (alpha-Fe2O3) superstructure with high coercivity
(Journal of Alloys and Compounds, 2012)
We found novel and superior magnetic properties of the hematite (alpha-Fe2O3) that originate from an internal microstructure of particles and strong inter-particle interactions between nanocrystal sub-units. The hematite ...
Characterization of partially inverse spinel ZnFe2O4 with high saturation magnetization synthesized via soft mechanochemically assisted route
(Journal of Physics and Chemistry of Solids, 2014)
ZnFe2O4 was prepared by a soft mechanochemical route from two starting combinations of powders: (1) Zn(OH)(2)/alpha-Fe2O3 and (2) Zn(OH)(2)/Fe(OH)(3) mixed in a planetary ball mill. The mechanochemical treatment provoked ...
Ab initio study of electronic, magnetic and optical properties of CuWO4 tungstate
(Computational Materials Science, 2011)
Ab initio calculations based on the density-functional theory have been employed to study the electronic and magnetic properties of copper tungstate CuWO4, as well as its optical characteristics in the ultraviolet region, ...
Effects of sintering on the structural, micro structural and magnetic properties of nanoparticle manganite Ca1-xGdxMnO3 (x=0.05, 0.1, 0.15, 0.2)
(Ceramics International, 2015)
Nanocrystalline manganites Ca1-xGdxMnO3 (x=0.05, 0.1, 0.15, and 0.2) were synthesized by a modified glycine-nitrate procedure and subjected to a systematic investigation regarding the effects of calcination and sintering ...
Re-formation of metastable epsilon-Fe2O3 in post-annealing of Fe2O3/SiO2 nanostructure: Synthesis, computational particle shape analysis in micrographs and magnetic properties
(Ceramics International, 2017)
Several Fe2O3/SiO2 nanostructures were synthesized by the combination of the microemulsion and a sol-gel methods. Based on X-ray powder diffraction (XRD) and magnetic measurements (giant coercivity similar to 2.13 T) we ...
