Charge Transport in Manganites: Hopping Conduction, the Anomalous Hall Effect and Universal Scaling
Y. Lyanda-Geller, S. H. Chun, M. B. Salamon +5
The low-temperature Hall resistivity ρ_{xy} of La_{2/3}A_{1/3}MnO_3 single crystals (where A stands for Ca, Pb and Ca, or Sr) can be separated into Ordinary and Anomalous contribut…
Correlated Polarons in Dissimilar Perovskite Manganites
C. S. Nelson, M. v. Zimmermann, J. P. Hill +10
We report x-ray scattering studies of broad peaks located at a (0.5 0 0)/(0 0.5 0)-type wavevector in the paramagnetic insulating phases of La_{0.7}Ca_{0.3}MnO_{3} and Pr_{0.7}Ca_{…
Commensurate-Incommensurate transition in the melting process of the orbital ordering in Pr0.5Ca0.5MnO3: neutron diffraction study
R. Kajimoto, H. Yoshizawa, Y. Tomioka +1
The melting process of the orbital order in Pr0.5Ca0.5MnO3 single crystal has been studied in detail as a function of temperature by neutron diffraction. It is demonstrated that a…
Short-range polaron correlations in the ferromagnetic La(1-x)Ca(x)MnO(3)
Pengcheng Dai, J. A. Fernandez-Baca, N. Wakabayashi +3
We use neutron scattering to demonstrate the presence of lattice polarons and their short-range correlations for several samples of LaCaMnO in the Ca doping range $…
X-ray Resonant Scattering Studies of Orbital and Charge Ordering in PrCaMnO
M. v. Zimmermann, C. S. Nelson, J. P. Hill +10
We present the results of a systematic x-ray scattering study of the charge and orbital ordering in the manganite series PrCaMnO with =0.25, 0.4 and 0.5. The tem…
Orbital-ordering-induced anomalous softening of the ferromagnetic spin waves in perovskite manganites
R. Kajimoto, H. Yoshizawa, H. Kawano-Furukawa +3
Spin wave excitations were measured in the ferromagnetic phase of NdSrMnO by neutron scattering. This compound is located in proximity to the A-type antiferro…
