Structural, microstructure, magnetic, and dielectric characterization of BaFe12O19/NiFe2O4ferrite nanocomposites
Abstract
BaFe12O19 and NiFe2O4 ferrite powders were synthesized separately using the sol gel auto-combustion method, and physically mixed in various weight ratios (100:0, 50:55, 40:60, 20:80, 0:100). The nanocomposites were heated at 1000 °C and characterized using XRD, SEM, VSM, and dielectric techniques. XRD analysis confirmed the presence of both hexagonal (BaFe12O19) and cubic (NiFe2O4) phases in the prepared nanocomposites. SEM micrographs revealed notable changes in the grain morphology and grain size with increasing nickel ferrite content. Magnetic hysteresis studies indicated that all BaFe12O19/NiFe2O4 nanocomposites exhibit multi-domain nature as reflected by the squareness ratio (
