Description

We have investigated spin phonon coupling in the strain coupled magnetoelectric SmFeO3/0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 (PMN-PT) composite in the temperature range of 300–650 K by Raman spectroscopy and magnetic measurements. The SmFeO3/PMN-PT composite shows sharp rise in magnetic moment across ferroelectric transition temperature (Tc) of PMN-PT. Around this transition temperature (Tc of PMN-PT), the temperature evolution of Raman spectra of the composite also shows anomalies in the phonon frequencies and line width corresponding to the SmFeO3 phase which indicate structural modifications in the SmFeO3 phase around Tc of PMN-PT. The observed structural, magnetic, and phonon anomalies of SmFeO3 around Tc of PMN-PT in SmFeO3/PMN-PT are attributed to spin-phonon coupling providing evidence of strong strain mediated magnetoelectric effects.
