“…Also some oxygen defects in the spinel ferrite structure can also get introduced, due to which a slight shifting of the ions takes place, which can change the bond lengths. 15,16 Earlier works on yttrium-substituted cobalt ferrites has already been established and many scientists have worked on this area and utilized such materials for various applications, like gas sensors, conducting multilayer chips, high-frequency devices, superconductors, microwave devices, and high-density recording media. Hasim et al discussed that the co-substitution of cerium and dysprosium in cobalt ferrites can improve their electrical and magnetic properties.…”
