The present work is focused on the effect of Fe(3+) replacement by rare earth-Ho(3+) ions and their influence properties MnFe2O4 ferrite. Ho(3+) substituted ferrite samples with chemical formula MnHoxFe2-xO4 were synthesized where substitution concentration was 0.0, 0.05, 0.1 0.15. self-ignited sol-gel method using nitrates respective elements. Powder X-ray diffraction, transmission electron microscopy, infrared spectroscopy, vibrating sample magnetometer (VSM) electrical measurements...
CoCrxFe2–xO4 (0 ≤ x 1.0) was synthesized by sol–gel auto combustion method using nitrates of respective elements and keeping 1:3 ratio metal nitrate to citrate. Representative sample investigated thermogravimeter/differential thermal analyzer (TG/DTA); then, all samples were annealed at 500 °C for 4 h. The broad peaks in the X-ray diffraction patters (XRD) evaluation transmission electron microscopy (TEM) indicate a fine particle nature particles. Scanning (SEM) analysis EDAX indicated that...
Dy3+ substituted Ni-Cu-Zn (Ni0.4Cu0.4Zn0.2DyxFe2−xO4) ferrite nanoparticles were obtained at 600 °C by synthesizing sol-gel auto-combustion method, and they exhibit a particle size of 12–21 nm. X-ray diffraction patterns confirm the presence secondary phase DyFeO3 Fe2O3 for samples. ferries doped with possess better grain structure growth than that pure ferrite. The saturation magnetization increases remarkably up to 81 emu/g increasing ions. increased related exchange interactions between...
Sol-gel-synthesized Co-Cu-Zn ferrite nanoparticles diluted with Dy3+ ions were investigated in terms of their structural, morphological, elastic, magnetic and dielectric properties. X-ray diffraction patterns showed the formation a single-phase cubic spinel structure. As concentration was increased, lattice length gradually increased from 8.340 to 8.545 Å, obeying Vegard's law. The Williamson-Hall (W-H) method employed observe change strain. Crystallite size obtained W-H plots followed...
In this work, the structural and magnetic properties of Al3+ substituted Ni-Zn ferrite powders were investigated. Ni0.7Zn0.3AlxFe2−xO4 (where x = 0.0–0.5) obtained by sol-gel auto combustion method. X-ray diffractometer, vibrating sample magnetometer, scanning electron microscopy, infrared spectroscopy, permeability used to study effects ions on properties. patterns reveal that all samples have single-phase cubic spinel structure. Infrared spectroscopy was locate absorption bands influence...
Ferrite samples of Li+ substituted MnFe2O4 nano particles were synthesized by sol-gel auto-combustion method. The obtained annealing at relatively low temperature 600 °C and characterized x-ray diffraction, transmission electron microscopy, vibrating sample magnetometry, infrared (IR) spectroscopy. Lattice parameter, density, specific surface area, porosity are found to increase, whereas bulk density crystallite size showed the decreasing trend with content. Splitting major absorption bands...
