Low energy excitations in crystalline perovskite oxides: Evidence from noise experiments
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report measurements of 1/f noise in a crystalline metallic oxide with perovskite structure down to 4.2K. The results show existence of localized excitations with a…

Optical Conductivity of Manganites: Crossover from Jahn-Teller Small Polaron to Coherent Transport in the Ferromagnetic State
M. Quijada, J. Cerne, J. R. Simpson +7
We report on the optical properties of the hole-doped manganites Nd_{0.7}Sr _{0.3}MnO_{3}, La_{0.7}Ca_{0.3}MnO_{3}, and La_{0.7}Sr_{0.3}MnO_{3}. The low-energy optical conductivity…
