Description:
Author(s): Mads Christof Weber, Mael Guennou, Hong Jian Zhao, Jorge Íñiguez, Rui Vilarinho, Abílio Almeida, Joaquim Agostinho Moreira, and Jens Kreisel We report a Raman scattering study of six rare-earth orthoferrites R FeO 3 , with R = La, Sm, Eu, Gd, Tb, Dy. The use of extensive polarized Raman scattering of SmFeO 3 and first-principles calculations enable the assignment of the observed phonon modes to vibrational symmetries and atomic displacements… [Phys.
