BaTiO3, a well reported perovskite ferroelectric material undergoes structural phase transitions under various temperatures. Growing crystals of BaTiO3 from stoichiometric melt always results in the hexagonal phase which is a high temperature phase, which subsequently remains meta-stable at room temperature. Single crystals of h-BaTiO3 were grown in air and oxygen atmosphere by floating zone furnace using four halogen lamps. The structure of grown crystal was monitored by powder X-ray diffraction. Various measurements like UV-Vis, Raman scattering, were carried out in order to analyse the optical and vibrational properties of h-BaTiO3. Efforts were made to grow single crystals of Ba0.9Zn0.1Ti0.9Mn0.1O3 composition in order to induce ferromagnetism in BaTiO3.
