Abstract
Successful synthesis of single phase multiferroic LaFeO3 and its lattice dynamic study is presented. The LaFeO3 has been synthesized by sol-gel auto combustion citrate method. Powder of the sample sintered at 900 C-0, resulted in well crystalline orthorhombic single phase LaFeO3 as identified by X-ray diffraction (XRD) analysis. Crystallite size estimated by Debby Scherrer formula is in the range of 100 nm. Normal incident reflectivity spectra obtained at room temperature in the frequency range 30-7500 cm(-1) possess well resolved optical phonon. Typical insulator like reflectivity spectra have been observed and discussed in terms of phonon dynamics and its possible role in multiferroic properties for LaFeO3.
