Relaxation of dynamically disordered tetragonal platelets in the relaxor ferroelectric
Florian Pforr, Kai-Christian Meyer, Márton Major +4
The local dynamics of the lead-free relaxor (NBT-3.6BT) have been investigated by a combination of qua…
Crystal field parameters of the rare earth pyrochlores TiO ( = Tb, Dy, Ho)
M Ruminy, E Pomjakushina, K Iida +4
In this work we present inelastic neutron scattering experiments which probe the single ion ground states of the rare earth pyrochlores TiO ( = Tb, Dy, Ho). DyT…
First principles calculation and experimental investigation of lattice dynamics in the rare earth pyrochlores R2Ti2O7 (R=Tb, Dy, Ho)
M Ruminy, M Nunez Valdez, B Wehinger +15
We present a model of the lattice dynamics of the rare earth titanate pyrochlores R2Ti2O7 (R=Tb, Dy, Ho), which are important materials in the study of frustrated magnetism. The ph…
Influence of tetragonal platelets on the dielectric permittivity of 0.964NaBiTiO-0.036BaTiO
Florian Pforr, Márton Major, Wolfgang Donner +2
We study the temperature-dependent evolution of the octahedral tilt order in a lead-free relaxor ferroelectric and its impact on the ferroelectric properties. Using diffuse neutron…
Structural properties in Sr0.61a0.39Nb2O6 in the temperature range 10 K to 500 K investigated by high-resolution neutron powder diffraction and specific heat measurements
J. Schefer, D. Schaniel, V. Pomjakushin +5
We report high-resolution neutron powder diffraction on Sr0.61Ba0.39Nb2O6, SBN61, in the temperature range 15-500 K. The results indicate that the low-temperature anomalies (T<100K…
