Abstract
We report nanoparticles of Mn2+ doped Mg0.5Zn0.5âxMnxFe2O4 (x = 0, 0.125, 0.250, 0.375, 0.500) ferrites synthesized via co-precipitation route for hyperthermia applications. The prepared samples have been characterized by XRD, FT-IR, FE-SEM, VSM and Photoluminescence spectroscopy for various physical properties. The variation in structural parameters has been obtained with Mn2+ substitution. The confirmation of intrinsic vibration of metal ions at octahedral sites and tetrahedral sites obtained with the help of FT-IR spectra has been reported. The inception of soft-ferri-magnetic behaviour with Mn2+ substitution (x > 0) has been obtained. The variation in magnetic behaviour with Mn2+ substitution indicates enhancement in A-B super-exchange interaction. The confirmation of enhancement in A-B super-exchange interaction with the help of Yafet-Kittel angles and proposed cation distribution has also been reported. The room temperature photoluminescence spectra show a non-linear variation in band edge emission with Mn2+ substitution. The nanoparticles have shown soft ferri-magnetic behaviour for Mn2+ doped samples and results support the candidature of synthesized nanoparticles for hyperthermia applications.
