Structural, Morphological, and Magnetic Characterization of Green-Synthesized Cr3+Substituted Mg-Zn Ferrites

 The synthesis of Lemon Juice Mediated Cr2+ Doped Cu0.6CrxFe2o4 Ferrite Nanoparticles successfully. The structural studies reveals that the formation of spinal cubic crystal structure with crystallite size 26 - 33 nm. lattice constant a lies between 8.3674 8.4056. Morphological analysis shows this small spherical particles and grain size observed 29 - 38 nm. EDS confirm the purity of the sample and presence of Cu, Cr,Fe and O elements. FTIR shows two wave number around 541 and 431 Cm-1 with tetrahedral and octahedral stretching. The magnetic parameters obtained from VSM data shows the increased saturation magnetization (Ms) value by substitution of Cr2+.
