X-band electromagnetic properties of hydrothermally synthesized La1-xBixTiO3 (x=0.2-0.8) nanoparticles

The La1-xBixTiO3 (x = 0.2, 0.4, 0.6 & 0.8) (LBTO) nanoparticles were prepared via hydrothermal method. The diffraction study confirmed the polycrystalline nature samples. The microstructure of LBTO evidenced the presence of nanorods, and asymmetrical stones like nanoparticles. Raman spectra showed the formation of bands indicating the vibrations associated with titanium/bismuth/lanthanum (metals), and oxygen. Later, the electromagnetic properties like dielectric constant (epsilon '), dielectric loss (epsilon ''), magnetic permeability (mu '), and magnetic loss (mu '') were studied as a function of frequency from 8.2 to 12.4 GHz, and composition (x). The obtained results revealed a fact that the x = 0.2 & 0.6 samples exhibited the negative magnetic loss values suggesting microwave absorber applications.
