Abstract

This study aimed to investigate the effects of Co/Cu ratio on the
physical properties of Eu ion doped spinel nano-ferrites with the general
formula Cu1-xCoxEu0.025Fe1.975O4 and Cu1-xCoxEu0.1Fe1.9O4 (in which x= 0,
0.25, 0.50, 0.75, and 1 mol %) using a sol-gel auto-combustion technique.
The objective is to give a complete structural investigation of spinel ferrite
nanoparticles with more precision characterization employing (XRD, SEM,
EDAX, and FTIR), and examine how is Co-substitution .modifies the
magnetic prepared Cu1-xCoxEu0.025Fe1.975O4 and Cu1-xCoxEu0.1Fe1.9O4 spinel
nano-ferrites by (VSM).
To achieve this aim the following tasks were carried out:
1. Synthesizing Co-Cu Eu ion doped spinel nano-ferrites with the
formula Cu1-xCoxEuyFe2-yO4 (x= 0, 0.25, 0.50, 0.75 and 1) &
(y=0.025 and 0.1) using a sol-gel auto-combustion technique.
2. Identifying the phase composition and crystal structure of the
samples using X-ray diffraction (XRD) analysis.
3. Analyzing the surface morphology and grain size of the prepared
spinel ferrite samples through scanning electron microscopy
(SEM).
