Abstract

New molecules having the general formula A:N--B, where A:N-- is .alpha.-substituted conjugated cyclic amine, with N being the N atom; and B is an .alpha.-substituted cyclic radical. These materials have ferromagnetic properties and may be use in a variety of fields and particularly in any electromagnetooptical or magnetoresistive system.
