Аннотация

Mg2+ and Zn2+ substituted manganese ferrite nanoparticles were synthesized by chemical co-precipitation route. The synthesized samples were characterized by powder X-ray diffraction which confirms the cubic spinel ferrite structure and the crystallite size is in nanoscale. High resolution transmission electron microscope and scanning electron microscope were used to examine the surface morphology. The elemental composition and purity of the sample were confirmed from energy dispersive X-ray spectroscopic analysis. The band gap energy determined from UV-Vis absorption spectra reveals the semiconducting behavior of both the samples. The optical parameters calculated from the UV-Vis absorption spectra show that MMF has better optical property compared to ZMF nanocrystallites. The magnetic parameters determined using vibrating sample magnetometer show low coercivity, low squareness ratio exhibiting superparamagnetic behavior of the Mg2+ and Zn2+ substituted manganese ferrite nanoparticles which are important for technological applications.
