high as 35 K. The rush to room temperature was won by Miller and Epstein again who showed that V(TCNEh is a disordered ferrimagnet above room temperature. Verdaguer opened the saga of Prussian blue derivatives, finally reporting a ferri­ magnet comprising chromium(III), vanadium(II), and vanadium(III) which orders above room temperature. Nowadays the attempts to prepare molecular magnets which can be used at room temperature are continuing but at the same time there are many attempts to synthe­ sise molecular magnets which have properties which are difficult to be met in inor­ ganic magnets. Day reported an organic superconductor coexisting in the same lattice of a molecular paramagnet, while more recently Coronado reported a mole­ cular ferromagnet hosting in the lattice an organic conductor. This is an example of ferromagnetic conductor in which the active electrons, namely conducting and mag­ netic, are separated. Many efforts are currently done to investigate chiral magnets and to use light to influence the magnetic properties of the materials.
