Li ions for degaussing: A Prussian blue analogue with FeIII and CuII ions bridged by CN ligands underwent a ferromagnetic transition induced by ferromagnetic interactions between the Fe and Cu ions (see picture). Li ions penetrating into this ferromagnetic framework eliminated the ferromagnetic interaction and effected the formation of a paramagnetic framework. The ferromagnetism was recovered by extracting the Li ions.
