Bulk experimental evidence of half-metallic ferromagnetism in doped manganites
Guo-meng Zhao, H. Keller
We report precise measurements and quantitative data analysis on the low-temperature resistivity of several ferromagnetic manganite films. We clearly show that there exists a T^{4.…

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…

Evidence for the immobile bipolaron formation in the paramagnetic state of the magnetoresistive manganites
G. M. Zhao, Y. S. Wang, D. J. Kang +6
Recent research suggests that the charge carriers in the paramagnetic state of the magnetoresistive manganites are small polarons. Here we report studies of the oxygen-isotope effe…
