Temperature dependent Raman spectroscopy of polycrystalline bulk samples of La1−xCaxMnO3 (x = 0.0, and 0.3) synthesized by solid-state reaction method is presented. As the temperature is decreased, there is significant change in intensity and full width half maxima of all major Raman modes. This implies a structural rearrangement resulting in change of space group. This study brings out the variations in Raman spectra with temperature and also effect of Ca doping on A-site in the compound LaMnO3. Possible effect of Laser heating on the samples has also been discussed. Copyright © 2014 VBRI press.
