Effect of Europium Substitution on the Structural and Magnetic Properties of Nanocrystalline Cobalt Ferrite
A series of Europium-substituted cobalt ferrites (CoEuxFe2-xO4 with = 0.00, 0.10, 0.20, 0.30) were synthesized by hydrothermal method. The structural characterizations of all the prepared samples were done using XRD and FTIR. These studies confirmed the formation of single-phase spinel structure in all the compositions. The increase in the value of lattice parameter with increase in Europium concentration suggests the ... إقراء المزيد

Effect of chromium substitution on the structural and magnetic properties of nanocrystalline zinc ferrite
Single-phase Cr doped zinc ferrites have been synthesized by hydrothermal method. The crystal structure, microstructure, crystallite size and distribution, composition and magnetic properties of the synthesized nanoparticles were determined using X-ray powder diffraction, electron microscopies and vibrating sample magnetometry. Powders are composed of ultrafine spherical nanoparticles with a highly homogeneous elemental composition. The nanoparticles have partially inversed cubic spinel structure ... إقراء المزيد
