Structural, electrical and magnetic properties of nickel manganite obtained by a complex polymerization method
(Ceramics International, 2014)
Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized ...
BiFeO3 perovskites: A multidisciplinary approach to multiferroics
(Ceramics International, 2017)
Bismuth ferrite (BiFeO3) is one of the most studied multiferroic system with a large number of published articles. This is mainly because BiFeO3 material possesses both ferromagnetic and ferroelectric properties observed ...
Structure and magnetic properties of Co3O4/SiO2 nanocomposite synthesized using combustion assisted sol-gel method
(Ceramics International, 2016)
This paper reports on novel cobalt oxide nanoparticles (NPs) embedded in an amorphous silica (SiO2) matrix, synthesized using a modified sol-gel method. SEM and TEM images show as-synthesized particles to aggregate in the ...
Core-shell superparamagnetic iron oxide nanoparticle (SPION) clusters: TEM micrograph analysis, particle design and shape analysis
(Elsevier, 2016)
For the first time, particle shape analysis of silica coated iron oxide (maghemite/magnetite) nanoparticle clusters (core-shell nanostructures) is discussed using computational methods. We analyzed three samples of core-shell ...
Solution combustion synthesis method and magnetic properties of synthesized polycrystalline calcium manganite CaMnO3-delta powder
(Ceramics International, 2016)
We present a modified solution combustion synthesis method and measured magnetic properties of CaMnO3-delta (calcium manganite). The structure, morphology and magnetic properties of CaMnO3-delta were investigated by XRPD ...

Synthesis of hematite and iron oxyhydroxide nanocrystals by precipitation of Fe3+ ions inside oleic acid micelles
(Ceramics International, 2013)
alpha-Fe2O3 nanospheres with diameters of 20-40 nm and FeOOH nanorods with diameters of 150-200 nm and lengths of 0.5-1.0 mu m were synthesized via hydrolysis of Fe(NO3)(3) and FeCl3 solutions, respectively, in the presence ...
Modified self-propagating high-temperature synthesis of nanosized La0.7Ca0.3MnO3
(Ceramics International, 2013)
A modified solid-state combustion route was developed for the preparation of nanocrystalline manganite La0.7Ca0.3MnO3 in a single-step process, using metal nitrates and glucose/KNO3 redox mixture. The obtained sample was ...
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 of hexagonal YMnO3 from precursor obtained by the glycine-nitrate process
(Ceramics International, 2013)
A new synthesis route for obtaining a single-phase hexagonal YMnO3 was developed, based on the annealing of the amorphous precursor powder obtained by the glycine-nitrate combustion method. The process was monitored by XRD ...
