Abstract
Introduction: A chemical formula of nanocomposite 0.1 Bi2/3Cu3Ti4O12 -0.9 Bi3LaTi3O12 (BCLT-19) was prepared by semi wet route using metal nitrate and solid TiO2. The phase formation of Bi2/3Cu3Ti4O12 (BCT) and Bi3LaTi3O12 (BLT) was confirmed by an X-ray diffraction (XRD) study.
Methods: Transmission electron microscope (TEM) analysis showed a nanoparticle of size 14 ± 5 nm on average for BCLT-19 composites. Scanning electron microscope (SEM) images exhibited a tubular, spherical, and heterogeneous structure of grains. The root means square roughness, average roughness, and maximum area peak height were explained by atomic force microscopy (AFM).
Results: Study of magnetic properties was determined as weak antiferromagnetic to ferromagnetic in nature. The high dielectric constant (ε' = 3147 at 100Hz to 500 K) of BCLT-19 may be due to the existence of space charge polarization.
Conclusion: This paper studies the novel composite materials of BCLT-19 micro-structural properties. This study might be useful for future random-access memory devices and dielectric materials.
