MH2P2O7 (M = Co, Ni): Metamagnetic Interaction between the zigzag octahedral chains

Abstract

CoH2P2O7 and NiH2P 2O7, which contain edge-sharing zigzag octahedral chains, were hydrothermally synthesized and structurally characterized. Both compounds exhibit field-induced metamagnetic behavior because of the strong intrachain ferromagnetic and relatively weak interchain antiferromagnetic interactions. © 2007 American Chemical Society.
