Magnetic short and long range order in PbFeTaO
S. Chillal, S. N. Gvasaliya, D. Schroeter +5
PbFeTaO (PFT) belongs to the family of PbBBO which have inherent chemical disorder at the B-site. Due to this disorder, a complex magnet…
Microscopic Coexistence of Antiferromagnetic and Spin-Glass States
S. Chillal, M. Thede, F. J. Litterst +4
The disordered antiferromagnet \pfn (\pfns) is investigated in a wide temperature range by combining Mössbauer spectroscopy and neutron diffraction experiments. It is demonstrated…
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…
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…
Spin-glass state and long-range magnetic order in Pb(Fe1/2Nb1/2)O3
G. -M. Rotaru, B. Roessli, A. Amato +4
We have investigated the magnetic ground-state of the multiferroic relaxor ferroelectric \pfn with SR spectroscopy and neutron scattering. We find that a transition to a partial…
