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