Chemical switching of magnetic properties through topotactic lithium exchange in manganese(III) arsenate hydrate
Abstract
The switch in local Jahn–Teller distortions of the MnIIIO6 octahedra caused by the topotactic ion-exchange reaction of MnAsO4·H2O to give LiMnAsO4(OH) results in a novel switch from antiferromagnetic to ferromagnetic order within infinite Mn–O–Mn chains in the framework, although in both materials the overall order is antiferromagnetic.
