Anisotropic magnetic properties and magnetic ordering in molecular decamethylferrocenium tetracyanoethanide

Abstract We report magnetic susceptibility ( ξ spin (T)) and magnetization measurements for single crystals of the compound decamethylferrocenium tetracyanoethanide, (DMeFc)(TCNE), with the needle axis oriented parallel and perpendicular to the applied field. Magnetic ordering studies carried out using neutron diffraction show enhancement' of the Bragg peaks at temperatures less than 4.8K. The susceptibility for 16 K
