Phase transition of chemically doped uniaxial relaxor ferroelectric
Shravani Chillal, Dimitrios Koulialias, Severian Gvasaliya +4
We report a neutron scattering study of the ferroelectric phase transition in SrCeBaNbO (SBN-61:Ce). We find no evidence for a soft transverse…
Cube-shape diffuse scattering and the ground state of
A. Cervellino, S. N. Gvasaliya, B. Roessli +6
A quite unusual diffuse scattering phenomenology was observed in the single-crystal X-ray diffraction pattern of cubic perovskite BMT ($\mathrm{BaMg}_{1/3}\mathrm{Ta}_{2/3}\mathrm{…
The Structure and Low-Energy Phonons of the Nonferroelectric Mixed Perovskite: BaMg1/3Ta2/3O3
A. Cervellino, S. N. Gvasaliya, B. Roessli +5
The structure of BaMg1/3Ta2/3O3 (BMT) has been studied using X-ray scattering. The phonons have been measured and the results are similar to those of other materials with the perov…
Spin Glass ground state in MnCoSi
J. Teyssier, E. Giannini, V. Guritanu +4
We report the discovery of a new spin glass ground state in the transition metal monosilicides with the B20 crystallographic structure. Magnetic, transport, neutron and muon invest…
Study of diffuse scattering under hydrostatic pressure in PbMg1/3Nb2/3O3
G -M Rotaru, B Padmanabhan, S N Gvasaliya +5
We report measurements of the evolution of the diffuse scattering in a single crystal PbMg1/3Nb2/3O3 as a function of hydrostatic pressure. Upon applying pressure the diffuse scatt…
Diffuse scattering from the lead-based relaxor ferroelectric PbMg_1/3Ta_2/3O_3
A. Cervellino, S. N. Gvasaliya, O. Zaharko +6
The relaxor ferroelectric PbMg_1/3Ta_2/3O_3 was studied by single-crystal neutron and synchrotron x-ray diffraction and its detailed atomic structure has been modeled in terms of s…
