Structural and electrical properties of La3+ ions substituted MnFe2O4 ferrite nanoparticles synthesized via cost-effective reverse micelles strategy

Magnetic and structural properties of nickel zinc ferrite nanoparticles synthesized at room temperature

Nickel zinc ferrite nanoparticles (Ni0.20Zn0.44Fe2.36O4) have been produced at room temperature, without calcination, using a reverse micelle process. Particle size is approximately 7 nm as determined by x-ray powder diffraction and transmission electron microscopy. Saturation magnetization values are lower than anticipated, but are explained by elemental analysis, particle size, and cation occ...

Structural characteristics, electrical conduction and dielectric properties of gadolinium substituted cobalt ferrite

Gadolinium (Gd) substituted cobalt ferrites (CoFe2 xGdxO4, referred to CFGO) with variable Gd content (x = 0.0–0.4) have been synthesized by solid state reaction method. The crystal structure, surface morphology, chemistry, electrical conduction and dielectric properties of CFGO compounds have been evaluated. X-ray diffraction measurements indicate that CFGO crystallize in the inverse spinel ph...
