Polaron-mediated spin correlations in metallic and insulating LaMnO (=Ca, Sr, or Ba)
Joel S. Helton, Daniel M. Pajerowski, Yiming Qiu +6
Neutron spectroscopy measurements reveal short-range spin correlations near and above the ferromagnetic-paramagnetic phase transition in manganite materials of the form La$_{1-x}A_…
Evolution of the commensurate and incommensurate magnetic phases of the S = 3/2 kagome staircase Co3V2O8 in an applied field
Joel S. Helton, Ying Chen, Georgii L. Bychkov +4
Single crystal neutron diffraction studies have been performed on the S = 3/2 kagome staircase compound Co3V2O8 with a magnetic field applied along the magnetization easy-axis (H |…
Polaron formation in the optimally doped ferromagnetic manganites La0.7Ba0.3MnO3 and La0.7Ba0.3MnO3
Y. Chen, B. G. Ueland, J. W. Lynn +3
The nature of the polarons in the optimally doped colossal magnetoresistive (CMR) materials La0.7Ba0.3MnO3 (LBMO) and La0.7Sr0.3MnO3 (LSMO) is studied by elastic and inelastic neut…
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…
Low temperature mixed spin state of Co3+ in LaCoO3 evidenced from Jahn-Teller lattice distortions
V. Gnezdilov, K. -Y. Choi, Yu. Pashkevich +6
One- and multi-phonon excitations of the single crystalline LaCoO3 were studied using Raman spectroscopy in the temperature region of 5 K - 300 K. First-order Raman spectra show a…
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…
