Abstract

Studies will be conducted on magnetoelectric coupling in quadrupolar peroviskites through magnetoeletric, Raman, near infrared and of dielectric constant as a function of magnetic field measurements. This effect will be correlated with structural composition of samples and effects of pressure. (AU)
