Abstract

Nanoparticles of the La _0.9Sr _0.1MnO ₃ (LSMO) have been synthesized by using combustion method in which polyvinyl alcohol was used as fuel and an ion complexing agent. Thermogravimetric analysis shows the stable phase formation takes place at temperature above 700°C. The X-ray diffraction study of prepared sample confirms the rhombohedral phase formation. The texture coefficient (TC) has been calculated. The compositional analysis was carried out by EDAX pattern. The significant band at 532 cm ^-1 in the IR spectrum confirms the presence of characteristic band of LSMO. The nanocrystalline nature was corroborated by TEM micrographs and observed particle size about 20 nm. The frequency dependent dielectric constant (ε) shows the usual dispersion behavior and dielectric constant decreases with increase in frequency. The DC resistivity measurement with temperature indicates a semiconducting behavior of the LSMO sample.
