摘要: We present detailed studies on M-type barium ferrite (BaFe12O19, BaM) synthesized by the sol–gel combustion method that is calcined at 1000 °C, 1100 °C, and 1200 °C. In addition to structural properties, we THz optical dielectric constant conductivity response of this system as a function calcination temperature. From x-ray diffraction (XRD) studies, single-phase hexagonal structure established, crystallite size (Dhkl) was calculated be in range 26 nm–28.54 nm. The XRD patterns were analyzed evaluate lattice parameters (a, c, V) density (ρx). Home built terahertz time-domain spectroscopy performed investigate complex refractive index (ns) samples room temperature frequency 0.2 THz–1.2 THz. (es) (σs) deduced using data. BaM determined for temperatures
