A new scattering mechanism of acoustic phonons in relaxor ferroelectrics: the case of KTa_{1-x}Nb_xO_3

J. Toulouse, E. Iolin, B. Hennion +3

The complex interaction between transverse acoustic (TA) phonon, transverse optic (TO) phonon and polar nano-domains (PND) in the relaxor ferroelectric KTa1-xNbxO3 (KTN) is studied…
