Coexistence of localized and itinerant carriers near Tc in calcium-doped manganites
M. Jaime, P. Lin, S. H. Chun +3
We explore the possibility that polaronic distortions in the paramagnetic phase of LaCaMnO manganites persist in the ferromagnetic phase by considering the ob…

Hall-Effect Sign Anomaly and Small-Polaronic Conduction in (La_{1-x}Gd_x)_{0.67}Ca_{0.33}MnO_3
M. Jaime, H. T. Hardner, M. B. Salamon +3
The Hall coefficient of Gd-doped La_{2/3}Ca_{1/3}MnO_3 exhibits Arrhenius behavior over a temperature range from 2T_c to 4T_c, with an activation energy very close to 2/3 that of t…
