Abstract Polycrystalline Co-Zn nanoferrites doped with rare earth Dy 3+ ions having general chemical formula Co 0.9 Zn 0.2 x Fe 1.9-x O 4 (x = 0.0, 0.015, 0.03, 0.045 and 0.06) were synthesized via sol-gel auto-combustion route. Powder X-ray diffraction (XRD), scanning electron microscopy (SEM) Fourier transform Infrared Spectra (FTIR) performed to investigate the structural, microstructral, su...

Current study represents the effect of the size and synthesis method on the cation distribution of cobalt ferrite nanoparticles and on the magnetic properties. The nanoferrites have been synthesized through sol-gel auto-combustion method using metal nitrates as precursor and citrate as fuel. In order to obtain the fine and agglomerated-free particles, we have used salt-assisted combustion react...

We investigated the impact of cobalt (Co) incorporation on structural, optical, and magnetic properties ferrite Ni[Formula: see text]Co x Mn[Formula: text]Fe[Formula: text]O 4 , also known as NCMF for [Formula: text], 0.02, 0.04, which were successfully synthesized using a low-temperature sol-gel combustion process with nitrates cations citric acid (C 6 H 8 O 7 ) combustion/chelating agent. In ...

We report a microwave-combustion synthesis and structure-related physical properties of Ni0.4Zn0.6?xCrxFe2O4 (0.0 ? x 0.6) nanocrystals in study effects by substitution among cations with different oxidation states, Cr3+ for Zn2+. High-quality an average particle size 26–33 nm crystallite ranged 23–32 are revealed transmission electron microscopy (TEM) X-ray diffraction (XRD). Structural cation...
