Anisotropic thermoelectric transport in the Sr2RuO4-Ru eutectic system

Takeru Ito, Shogo Yoshida, Hiroshi Yaguchi +1

The Sr2RuO4-Ru eutectic system, in which metallic Ru inclusions are embedded in a Sr2RuO4 matrix, exhibits an enhanced superconducting onset temperature of about 3 K, known as the…

Carrier filtering effect for enhanced thermopower in a body-centered tetragonal ruthenate

Ryota Otsuki, Yoshiki J. Sato, Ryuji Okazaki +3

Charged carriers in solids diffuse from hot to cold sides under temperature gradient to induce the thermoelectric voltage. Carrier filtering effect, which only passes either electr…
