Abstract :

Ferrite powders with chemical composition MgxCo0.3Zn0.7-xFe2-yLayO4 for x = 0.1 to 0.5 in the step of 0.1 and y = 0.0 to 0.1 in the step of 0.025 were synthesized by the sol-gel auto-combustion method. The structural and electrical properties of the synthesized ferrites were investigated. X-ray diffraction technique were used to determine the structural parameters like lattice constant, X-ray density, particle size, hopping lengths and allied parameters. D. C. electrical resistivity measurements were taken by using two probe techniques. The hopping lengths ‘LA’ and ‘LB’ are found to increase with increase in Mg2+ and La3+ concentration. The d.c. resistivity decreases as the Mg2+ and La3+ content increases as well as the activation energy calculated from d.c. resistivity plots shows increasing trend.
