Abstract

Ferrite samples having the general formula MgxCu0.5-xZn0.5Fe2O4 were prepared using standard ceramic method. The structure characterization was made using X-ray diffraction and scanning electron microscopy. The effect of Mg2+ ion concentration, 0 ≤ x ≤ 0.5, on the mechanical and magneto-electric properties of the ferrites is investigated. It is found that the mechanical, magnetic and electrical properties depend on the Mg concentration. From the sintering experiments carried out between 800 and 1100 0 C it was established that a small Mg concentration, of 0.2, is sufficient to promote sintering at low temperature (1050 0 C) and to yield a dense material (4.5 g/cm3 ). High electrical resistivities were obtained for x = 0.2 – 0.5. Mechanical properties are improved..
