Effect of annealing temperature on magnetic and mössbauer properties of ZnFe2O4 nanoparticles by sol-gel approach
(Springer New York LLC, 2018)
In this study, spinel ZnFe 2 O 4 nanoparticles (NPs) were synthesized by citrate sol-gel route using nickel nitrates, ferric nitrates and citric acid by annealing at 900, 1000, and 1100 ? C. We reported the structural and ...
Synthesis and structural and magnetic characterization of BaZn x Fe12−x O19 hexaferrite: hyperfine interactions
(Springer New York LLC, 2017)
To study the effect of Zn substitution on structural magnetic properties and hyperfine interactions of barium hexaferrite, BaFe12−x Zn x O19 (0.0≤x≤0.3) hexaferrites were synthesized via sol-gel auto-combustion technique. ...
Mössbauer analysis and cation distribution of Zn substituted BaFe12O19 hexaferrites
(Springer New York LLC, 2018)
Barium hexaferrite is a well-known hard magnetic material. Doping using nonmagnetic cation such as Zn2+ were found to enhance magnetization owing to preferential tetrahedral site (4 f 1) occupancy of the zinc. However, the ...
Tracking of SPIONs in barley (Hordeum vulgare L.) plant organs during its growth
(Springer New York LLC, 2019)
Barley plants were grown in water solutions containing nutrient elements and superparamagnetic iron oxide nanoparticles (SPIONs), particularly the magnetite nanoparticles (Fe3O4; 15–20-nm particle size). No visible detection ...
The effect of austenitizing time on martensite morphologies and magnetic properties of martensite in Fe-24.5%Ni-4.5%Si alloy
(2007)
The effect of austenitizing time on the formation of martensite in Fe-24.5%Ni-4.5%Si alloy has been studied by means of transmission electronmicroscope (TEM), scanning electronmicroscope (SEM) and Mössbauer spectroscopy ...

Structural, morphological, optical, cation distribution and Mössbauer analysis of Bi3+ substituted strontium hexaferrite
(Elsevier Ltd, 2016)
Single-phase M-type hexagonal ferrites, SrBixFe12−xO19 (0.0≤x≤1.0), were prepared by a co-precipitation assisted ceramic route. The influence of the Bi3+ substitution on the crystallization of ferrite phase has been examined ...
Structural investigation and hyperfine interactions of BaBixLaxFe12−2xO19 (0.0≤x≤0.5) hexaferrites
(Elsevier Ltd, 2016)
Barium hexaferrite, BaFe12O19, substituted by Bi3+ and La3+ (BaBixLaxFe12−2xO19 where 0.0≤x≤0.5) were prepared by solid state synthesis route. The effect of substituted Bi3+ and La3+ ions on the structure, morphology, ...
Electrical properties and hyperfine interactions of boron doped Fe3O4 nanoparticles
(Academic Press, 2015)
The single spinel phase nano-structured particles of FeBxFe2-xO4 (x = 0.1, 0.2, 0.3, 0.4 and 0.5) were synthesized by the glycothermal method and the effect of B3+ substitution on structural and dielectric properties of ...
