The broad Brillouin doublets and central peak of KTaO_3
E. Farhi, A. K. Tagantsev, B. Hehlen +3
The incipient ferroelectric KTaO3 presents low-T Brillouin spectra anomalies,e.g. a broad central peak (CP), and some additional Brillouin doublets (BD), whose origin is interprete…

The Broad Brillouin Doublet and CP of Ktao_3 : Second Sound vs. Two-Phonon Difference Scattering
E. Farhi, A. K. Tagantsev, B. Hehlen +3
Low-T Brillouin spectra of the incipient ferroelectric KTaO3 exhibit a broad central peak (CP), and additional Brillouin doublets (BD), that can both be related to phonon-density f…

Low energy phonon spectrum and its parameterization in pure KTaO3 under 80 K
E. Farhi, A. K. Tagantsev, R. Currat +3
High resolution data on low energy phonon branches (acoustic and soft optic) along the three principal symmetry axes in pure KTaO3 were obtained by cold neutron inelastic scatterin…
