摘要：Al3+ substituted Mn-Zn-Fe with a chemical formula Mn Zn AlxFe O and 0.5 0.5 2-x 4 Cr3+ substituted Mg-Zn-Fe with a chemical formula Mg Zn CrxFe O were 0.5 0.5 2-x 4 synthesized by sol-gel auto-combustion method. The samples were obtained by annealing at relatively low temperature at 600 ºC and characterized by X-ray diffraction (XRD). Lattice constant is decreased in both the system with the increasing substitution of Al and Cr ions. Ion jump length found to decrease with the increase of Al3+ in Mn-Zn- Fe, similar results were observed for Cr3+ substituted Mg-Zn-Fe. All the allied parameters such as tetrahedral bond (dAX), octahedral bond (dBX), tetra edge (dAXE) and octahedral edge (dBXE) shows decreasing trend in both the Mn-Zn-Al-Fe and Mg- Zn-Cr-Fe systems.
