The crucial importance of the $t_{2g}$--$e_g$ hybridization in transition metal oxides

Sylvain Landron, Marie-Bernadette Lepetit

We studied the influence of the trigonal distortion of the regular octahedron along the (111) direction, found in the $\mathrm{Co}{\mathrm{O}}_2$ layers. Under such a distortion the $t_{2g}$ orbit…
