Impurity-induced spin density wave in the thermoelectric layered cobaltite [Ca${}_2$CoO${}_3$]${}_{0.62}$[CoO${}_2$]

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…
