Abstract

Polycrystalline samples of mixed ferrite Mnl −x Cd x Fe2O4, wherex = 0, 0.2, 0.4, 0.6 and 0.8, were studied by X-ray analysis and d.c. electrical conductivity. lt was found that the calculated lattice parameter (a 0) increases from 0155 to 0.861 nm according to increases inx from 0 to 0.8. The apparent density and theoretical density exhibit the same behaviour. lt was also found that the activation energy of the conduction mechanism and log ϱ27° C increase with increasing cadmium content, which affect the exchange interaction mechanism in tetrahedral (A) sites and octahedral (B) sites.
