Abstract
Multiferroic of strontium titanate and magnesium ferrite nanocomposites with chemical formula x SrTiO3 + (1 − x) MgFe2O4; x = 0, 0.6, 0.7, 0.8, 0.9 and 1.0 have been synthesized through sol gel auto-combustion pathway. The blending is based on ball milling method. The lattice parameters and crystallite size of the combination nanocomposites were constant with different ratios of SrTiO3. FE-SEM revealed that the grain size decreased with x. The magnetization Ms was carried out using vibrating sample magnetometer at room temperature while the relative permeability µr was studied as a function of temperature at a constant frequency. Both saturation magnetization and relative permeability decreased with various increments of SrTiO3. DC electrical resistivity and (P–E) loops measurements were investigated. The dielectric properties and DC resistivity were enhanced. Such promising results are prospective requests for sensors, high frequency applications and stage memories.
