- Abstract
We studied the effect of structural change on the spin-phonon coupling in doped BiFeO3 (BFO) films (Bi0.8La0.1Nd0.1FeO3) grown on SrTiO3 (001) substrate. The temperature-dependent Raman studies show phonon anomalies in the vicinity of magnetic ordering temperature TN owing to the spin-phonon coupling. Doped films exhibit strong anomalies in the line widths of Raman bands around TN revealing the presence of strong spin-lattice coupling. The modification in structure as a result of A-site doping in BFO films plays an important role in controlling the nature of spin-phonon coupling. Copyright © 2014 John Wiley & Sons, Ltd.
