Low-dimensional exchange interactions, structural deformation, and antiferromagnetic ordering in lithium manganite LiMnO2
Structure deformation in lithium manganite LiMnO2 has been analyzed. It is shown that suppression of the Jahn-Teller effect with a decrease in temperature is related to striction effects, which are caused by intercluster exchange interactions. It is concluded that low-dimensional interactions play an important role in the formation of magnetic properties of lithium manganite.
