| Popis: | The main goal of this study is to analyze the magnetic, dielectric, and magneto-dielectric characteristics of Pb1− x La x Ti1− x O 3 - (Ba1–3 x Nd2 x )4Co2Fe36O60 (where x = 0.25) composite material at various temperatures T1-T3 (i.e 1100°C ,1200°C, 1300°C respectively). The X-ray diffraction investigation has been introduced in order to pinpoint the creation of the U-type hexaferrite phase. SEM micrographs reveal that sample sintered at T2 reached the maximum value of grain size and the largest experimental density value of 6.14 g/cm3 due to the composite material's intensified grain growth. The magnetic investigations further indicate that the sample T2 achieved the highest remnant magnetization, measuring 1.550 emu/g, revealing the accuracy of the sintering temperature. The magneto-dielectric investigations demonstrate the presence of multiferroicity in all samples, and came to the conclusion that sample T2 exhibits the highest magneto-dielectric response of 41.99 at 1.2 Tesla and a magneto-dielectric coefficient (γ) of around 0.7609 g2/emu2. Numerous metrics, including nyquist plots, impedance, electrical modulus, dielectric constant, and conductivity, were carefully examined in order to determine the electrical properties of the proposed sample. It was found that sample T2 produced the enhanced results and had the right temperature for the substance to develop. |
