Tunable orbital susceptibility in $\alpha$-${\mathcal{T}}_3$ tight-binding models

F. Piéchon, J-N. Fuchs, A. Raoux +1

We study the importance of interband effects on the orbital susceptibility of three bands $\alpha$-${\mathcal{T}}_3$ tight-binding models. The particularity of these models is that the coupl…
