High-field magnetization and magnetoresistance of the -site ordered perovskite oxide CaCuTiRuO~()
T. Kida, R. Kammuri, M. Hagiwara +4
We have measured high-field magnetization and magnetoresistance of polycrystalline samples of the A-site ordered perovskite CaCu3Ti4-xRuxO12 (x=0 - 4) utilizing a non-destructive p…
Structure-related transport properties of A-site ordered perovskite Sr3ErMn4-xGaxO10.5-d
W. Kobayashi, T. Ishibashi
We report x-ray diffraction, resistivity, thermopower, and magnetization of Sr3ErMn4-xGaxO10.5-d, in which A-site ordered tetragonal phase appears above x=1, and reveal that the sy…
Thermal rectification in bulk materials with asymmetric shape
D. Sawaki, W. Kobayashi, Y. Moritomo +1
We investigate thermal rectification in a bulk material with a pyramid shape to elucidate shape dependence of the thermal rectification, and find that rectifying coefficient R is 1…
Dominant role of impurity scattering over crystalline anisotropy for magnetotransport properties in the quasi-1D Hollandite Ba1.2Rh8O16
Alain Pautrat, Wataru Kobayashi
Angular magnetotransport measurements have been performed to tackle the origin of the magnetoresistance in the quasi-1D Hollandite Ba1.2Rh8O16. Three samples of different impuritie…
An oxide thermal rectifier
W. Kobayashi, Y. Teraoka, I. Terasaki
We have experimentally demonstrated thermal rectification as bulk effect. According to a theoretical design of a thermal rectifier, we have prepared an oxide thermal rectifier made…
CaCu_3Ti_4O_12/CaTiO_3 Composite Dielectrics: A Ba/Pb-free Ceramics with High Dielectric Constants
W. Kobayashi, I. Terasaki
We have measured dielectric properties of CaCuTiO ( = 0, 0.1, 0.5, 1, 1.5, 2, 2.9 and 3), and have found that CaCuTiO (a composite…
