| Research Abstract |
We synthesized different exotic oxide thin film and polycrystalline pellets. We observed electromagnons in CoCr_2O_4 thin film using terahertz time-domain spectroscopy, which is the first such observation for spinel multiferroic. Raman spectroscopy shows transit phonon mode on CoCr_2O_4. Photoinduced effect has been observed in a manganite thin film using visible pump terahertz probe spectroscopy.
