Multi-scale Phase Modulations in Colossal Magnetoresistance Manganites
K. H. Kim, M. Uehara, V. Kiryukhin +1
Extensive experimental results are presented on the multi-scale phase modulation phenomena observed in colossal magnetoresistance manganites. Two key types of phase inhomogeneities…

High Temperature Charge-Ordering Fluctuation in Manganites
K. H. Kim, M. Uehara, S-W. Cheong
High temperature (T) studies of La_{1-x}Ca_{x}MnO_{3} show that charge and phonon transport is significantly suppressed in a narrow doping region of x~1/2 and in a wide T range up…

Giant Peak of the 1/f Noise at the Metal-Insulator Transitions in Low-Tc CMR Manganites: Evidence of the Percolation Threshold at Tc
V. Podzorov, M. Uehara, M. E. Gershenson +1
We observed a dramatic peak in the 1/f noise at the metal-insulator transition (MIT) in low-Tc manganites. This many-orders-of-magnitude noise enhancement is observed for both poly…
