    • Abstract

       

      Spinal ferrites having the general formula Co$_{1-x}$Zn$_{x}$Fe$_{2-x}$Al$_{x}$O4 ($x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6$) were prepared using the wet chemical co-operation technique. The samples were annealed at 800°C for 12 h and were studied by means of X-ray diffraction, magnetization and low field AC susceptibility measurements. The X-ray analysis showed that all the samples had single-phase cubic spinel structure. The variation of lattice constant with Zn and Al concentration deviates from Vegard's law. The saturation magnetization $\sigma_{s}$ and magneton number $n_{B}$ measured at 300 K using high field hysteresis loop technique decreases with increasing 𝑥, suggesting decrease in ferrimagnetic behaviour. Curie temperature $T_{C}$ deduced from AC susceptibility data decreases with 𝑥, suggesting a decrease in ferrimagnetic behaviour.
