Intrinsic pinning property of FeSe0.5Te0.5
M. Migita, Y. Takikawa, M. Takeda +5
The intrinsic pinning properties of FeSe0.5Te0.5, which is the superconductor with Tc of about 14 K, were studied by the analysis of magnetization curves by the extended critical s…
New anti-perovskite-type Superconductor ZnNyNi3
Masatomo Uehara, Akira Uehara, Katsuya Kozawa +1
We have synthesized a new superconductor ZnNyNi3 with Tc ~3 K. The crystal structure has the same anti-perovskite-type such as MgCNi3 and CdCNi3. As far as we know, this is the thi…
Carrier doping to pseudo-low-dimensional compound La2RuO5
Masatomo Uehara, Kenich Ashikawa, Yoshimasa Aka +1
Hole carrier doping has been tried to pseudo-low-dimensional material La2RuO5 by substituting La3+ with Cd2+. Single phased samples of La2-xCdxRuO5 with x up to 0.5 have been succe…
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…
Thermal/Electronic Transport Properties and Two-Phase Mixtures in La_{5/8-x}Pr_{x}Ca_{3/8}MnO_{3}
K. H. Kim, M. Uehara, C. Hess +2
We measured thermal conductivity, k, thermoelectric power, S, and dc electric conductivity, sigma, of La_{5/8-x}Pr_{x}Ca_{3/8}MnO_{3}, showing an intricate interplay between metall…
