Abstract

The present investigation was aimed to synthesize bismuth strontium manganite of composition Bi0.6Sr0.4MnO3 ceramic by low cost solid state technique. The ceramic showed orthorhombic crystal structure with micro-rod like surface morphology. The crystallite size was 34nm, with preferential orientation in (111) plane with TC of 2.15. On the basis of Zener polaron model and conventional model, possible Raman vibrational modes in bismuth strontium manganites have been assigned.
