Neutron powder diffraction study of NaMn 2 O 4 and Li 0.92 Mn 2 O 4 : Insights on spin-charge-orbital ordering

The authors study a charge-orbital-spin correlation of high-pressure synthesized quasi-one-dimensional NaMn${}_{2}$O${}_{4}$ and Li${}_{0.92}$Mn${}_{2}$O${}_{4}$ using a low-temperature neutron powder diffraction.
