Abstract :
Nano-sized magnesium-doped Li-Zn mixed ferrite system, Li0.25Mg0.5-xZnxFe2.25O4 where X varies from 0 to 0.5 in steps of 0.1 has been prepared by novel solution combustion method using oxalyl-dihydrazide as capping agent and were characterised by X-ray diffraction, infrared, Mössbauer studies and transmission electron microscopy (TEM). The magnetic and electrical properties of the nanoparticles have been investigated by vibrating sample magnetometer and two-probe method, respectively, and results are compared with bulk materials. TEM and electrical studies reveal the formation of one-dimensional semiconducting nanorods that find an extensive application in lithium batteries and in the fast-paced miniaturisation of modern electronic devices. The variation in dielectric constant with frequency has been studied.
