A minimal electrostatic theory for the Seebeck coefficient in liquids

Wataru Kobayashi

The Seebeck coefficient in liquids often reaches the mV/K range, yet its microscopic origin remains unclear due to the complexity of electrolyte systems. Here we propose a minimal…

Analytical expression of negative differential thermal resistance in a macroscopic heterojunction

Wataru Kobayashi

Heat flux () generally increases with temperature difference in a material. A differential coefficient of against temperature () is called differential thermal conductanc…

Thermopower in transition-metal perovskites

Wataru Kobayashi

High-temperature thermopower is interpreted as entropy that a carrier carries. Owing to spin and orbital degrees of freedom, a transition metal perovskite exhibits large thermopowe…

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…
