Multilayered Ferromagnets Based on Hybrid Organic-Inorganic Derivatives

Supramolecular multilayered ferromagnets in which metal layers are interleaved with iminonitroxide benzoate radical anions have been synthesized and characterized by the authors. The structure of these novel compounds (see cover) consists of stacks of alternating organic–inorganic layers. Long-range ferromagnetism is evidenced by magnetic and electroparamagnetic resonance (EPR) measurements, and shows clear interaction between the two sub-networks. In this respect, this new class of hybrid magnets differs markedly from classical intercalated layer compounds.
