Synthesis and characterization of electrospun NiCoCdNdFeO4 nanofibers
(Elsevier B.V., 2020)
We report here the production of novel Ni0.5Co0.5−xCdxNd0.02Fe1.78O4 nanofibers (NFs) (0.00 ≤ x ≤ 0.25) via electrospinning method with using polyvinylpyrrolidone (PVP) as a polymer agent. The investigation of the partial ...
Microstructural, optical, and magnetic properties of vanadium-substituted nickel spinel nanoferrites
(Springer New York LLC, 2019)
The current study investigates the impact of vanadium substitution on the structural, magnetic, and optical properties of NiFe2−xVxO4 (x ≤ 0.3) nanoparticles (NPs) produced by the cost-effective sol-gel route. The as-prepared ...
Tb3+ substituted strontium hexaferrites: Structural, magnetic and optical investigation and cation distribution
(Chinese Society of Rare Earths, 2019)
In this study, SrFe12−xTbxO19 (0.00 ≤ x ≤ 0.1) hexaferrites (HFs) were prepared successfully by citrate sol-gel approach. X-ray powder diffraction analyses affirm the hexagonal structure of products. Impurity phase starts ...
Tailored microstructures, optical and magnetic qualities of strontium hexaferrites: Consequence of Tm3+ and Tb3+ ions Co-substitution
(Elsevier Sci Ltd, 2019)
Terbium (Tb) and Thulium (Tm) co-doped strontium hexaferrites (SHFs), with composition SrFe12-2xTbxTmxO19 (0.00 <= x <= 0.04), were prepared via sol-gel auto-combustion method. The effect of Tb3+ and Tm3+ (as codopants) ...
Ultrasonic synthesis, magnetic and optical characterization of Tm(3+)and Tb3+ ions co-doped barium nanohexaferrites
(Academic Press Inc Elsevier Science, 2020)
This study investigated the structural, optical and magnetic properties of BaTmxTbxFe12-2xO19(x <= 0.05) nanohexaferrites (NHFs) produced by ultrasonic assisted sol-gel combustion approach. The structure of all samples was ...
Strong correlation between Dy3+ concentration, structure, magnetic and microwave properties of the [Ni0.5Co0.5](DyxFe2-x)O-4 nanosized ferrites
(Elsevier Science Inc, 2020)
The dysprosium ions (Dy-3(+))-substituted nanosized ferrites (NFs) of composition [Ni0.5Co0.5](DyxFe2-x)O-4 (x <= 0.08) were prepared using the citrate gel process. To analyse the magnetic properties of the samples, the ...
SrCoxZrxFe12-2xO19 and SrNixZrxFe12-2xO19 hexaferrites: A Comparison Study of AC Susceptibility, FC-ZFC and hyperfine interactions
