Spin-charge-orbital ordering in hollandite-type manganites studied by model Hartree-Fock calculation

Makoto Fukuzawa, Daiki Ootsuki, Takashi Mizokawa

We investigate spin-charge-orbital ordering in a Mn${}^{3+}$/Mn${}^{4+}$ mixed valence state on a hollandite-type lattice using unrestricted Hartree-Fock calculation on a multi-band Mn…
