Microstructure and Electromagnetic Properties of Y3+ Substituted Mg-Mn Nanocrystalline Ferrites Via Hydrothermal Procedure

Abstract

Mg[Formula: see text]Mn[Formula: see text]YxFe[Formula: see text]O4 ([Formula: see text], 0.025, 0.050 and 0.075) nanocrystalline is synthesized via hydrothermal technique. Single cubic spinel phase is confirmed by XRD and the formation of Mg[Formula: see text]Mn[Formula: see text]YxFe[Formula: see text]O4 is verified by EDS. The average size of the nanoferrites is around 80 nm, which is examined by TEM image. Y[Formula: see text] substituted Mg-Mn nanoferrites exhibit low saturation magnetization ([Formula: see text] and coercivity ([Formula: see text]. Especially, the nanoferrites with [Formula: see text] show the lowest [Formula: see text] and [Formula: see text] of 46.96[Formula: see text]emu/g and 12.04[Formula: see text]Oe, respectively. The ferrite composites present that the resistivity and the magnetic loss are less than [Formula: see text] and 0.7 in the range of 2–18[Formula: see text]GHz, respectively. The low coercivity and high resistivity indicate that the addition of Y[Formula: see text] contributes to the synthesis of the excellent soft magnetic materials.
