Effects of successive annealing on high-field electrical transport and the upper critical field in S-substituted FeTe

Ryosuke Kurihara, Satoshi Hakamada, Masaki Kondo +3

Since iron-based superconductors have been discovered, many scientists have focused on their characteristic properties, such as an unconventional mechanism and a high upper critica…

Impurity-induced spin density wave in the thermoelectric layered cobaltite [Ca $_{2}$ CoO $_{3}$ ] $_{0.62}$ [CoO $_{2}$ ]

Motoya Takenaka, Shogo Yoshida, Yoshiki J. Sato +1

We investigate the Sn-substitution effect on the thermoelectric transport properties of the layered cobaltite [Ca $_{2}$ CoO $_{3}$ ] $_{0.62}$ [CoO $_{2}$ ] single crystals, which exhibit a non…

Transverse thermoelectric conversion in the mixed-dimensional semimetal WSi $_{2}$

Shoya Ohsumi, Yoshiki J. Sato, Ryuji Okazaki

Materials with axis-dependent conduction polarity are known as $p \times n$ -type or goniopolar conductors that can be used for transverse thermoelectric devices, allowing the longit…
