Lattice dynamics in the paraelectric phase of PbHfO studied by inelastic X-ray scattering

R. G. Burkovsky, D. Andronikova, Yu. Bronwald +6

We report the results of an inelastic X-ray scattering study of the lattice dynamics in the paraelectric phase of the antiferroelectric lead hafnate PbHfO. The study reveals an…

Lattice dynamics and antiferroelectricity in PbZrO tested by X-ray and Brillouin light scattering

R. G. Burkovsky, A. K. Tagantsev, K. Vaideeswaran +13

We report the results of comprehensive study of the critical dynamics of the prototype perovskite antiferroelectric PbZrO. The combination of inelastic X-ray and diffuse X-ray…

Temperature independent diffuse scattering and elastic lattice deformations in relaxor PbMg1/3Nb2/3O3

R. G. Burkovsky, S. B. Vakhrushev, K. Hirota +1

The results of diffuse neutron scattering experiment on PbMg1/3Nb2/3O3 single crystal above the Burns temperature are reported. It is shown that the high temperature elastic diffus…

A new model of correlated disorder in relaxor ferroelectrics

A. Bosak, D. Chernyshov, S. Vakhrushev +1

We propose a simple phenomenological picture to explain the unusual dielectric properties of the proto-typical ferroelectric relaxor lead magnesium niobate-titanate (PMN-PT). Our m…

A reassessment of the Burns temperature and its relationship to the diffuse scattering, lattice dynamics, and thermal expansion in the relaxor PMN

P. M. Gehring, H. Hiraka, C. Stock +5

We have used neutron scattering techniques to characterize the diffuse scattering and lattice dynamics in single crystals of the relaxor PMN from 10K to 900K. We observed two disti…

Diffuse neutron scattering in relaxor ferroelectric PbMg1/3Nb2/3O3

Sergey Vakhrushev, Alexandre Ivanov, Jiri Kulda

High energy resolution neutron spin-echo spectroscopy has been used to measure intrinsic width of diffuse scattering discovered earlier in relaxor ferroelectric crystals. The aniso…
