X-ray and neutron diffraction studies of coupled structural phase transitions in DyBaCoO
Yu. P. Chernenkov, V. P. Plakhty, A. G. Gukasov +6
A structural transition at K from the to phase is found to coincide with an anomaly of resistivity. Another structural phase transition doubling the la…
Magnon Bose condensation in symmetry breaking magnetic field
S. V. Maleyev, V. P. Plakhty, S. V. Grigoriev +2
Magnon Bose condensation (BC)in the symmetry breaking magnetic field is a result of unusual form of the Zeeman energy, which has terms linear in the spin-wave operators and terms m…
Temperature excitation of the Co3+ triplet spin-state in LaCoO3 determined by polarized neutron diffraction
V. P. Plakhty, P. J. Brown, B. Grenier +4
The magnetic moment induced by an external magnetic field of 5.8 T on the Co3+ ions in LaCoO3 has been measured by polarized neutron diffraction. Measurements were made at 100 K, n…
Spin structure and magnetic phase transitions in TbBaCo2O5.5
V. P. Plakhty, Yu. P. Chernenkov, S. N. Barilo +5
Spin ordering in TbBaCo2O5.5 and its temperature transformation is studied. Polymorphism due to the oxygen ordering with the average content close to 5.5 is investigated. One of ce…
X-ray Diffraction Study of Superstructure in GdBaCo2O5.5
Yu. P. Chernenkov, V. P. Plakhty, V. I. Fedorov +3
A single crystal of GdBaCo2O5.47(2) has been studied by means of X-ray diffraction. Appearance of superstructure reflections at T = 341.5(7) K gives an evidence of continuous trans…
