Reply to "Comment on `Evidence for the immobile bipolaron formation in the paramagnetic state of the magnetoresistive manganites'"
Guo-meng Zhao
Zhao et al. [Phys. Rev. B 62, R11 949 (2000)] reported studies of the oxygen-isotope effects on the intrinsic resistivity and thermoelectric power in the paramagnetic state of seve…
Evidence for small or intermediate-size polarons in the ferromagnetic state of manganites
Guo-meng Zhao, D. J. Kang, W. Prellier +4
Oxygen-isotope effects on the intrinsic resistivity have been studied in high-quality epitaxial thin films of La_{0.75}Ca_{0.25}MnO_{3} and Nd_{0.7}Sr_{0.3}MnO_{3}. We found that t…
Oxygen isotope effects in high-quality thin films of manganites: Quantitative constraints on the physics of manganites
G. M. Zhao, D. J. Kang, W. Prellier +4
Oxygen isotope effects on the transport properties have been studied in high-quality epitaxial thin films of La_{0.75}Ca_{0.25}MnO_{3} and Nd_{0.7}Sr_{0.3}MnO_{3}. In the paramagne…
Kinetics of electric field induced oxygen ion migration in epitaxial metallic oxide films
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report the observation of curent induced change of resistance of thin metallic oxide films. The resistance changes at a very low current (current density $J \geq 1…
