Abstract
A series of Mg0.8Zn0.2CrxFe2-xO4 (0 <= x <= 0.025) nanoferrites were prepared by citratenitrate auto-combustion method. X-ray diffraction assured the formation of the ferrites in nanoscale and in single phase spinel structure. The magnetic and mechanical properties were investigated. All the elastic moduli values increase slowly and steadily with increasing Cr3+ content reaching the critical composition x=0.02. The magnetic parameters increased up to x=0.02 and then decreased with further Cr doping. Versatile applications were recommended owing to the porous nature of the nanoferrites.
