On the possibility of an organic magnet

Abstract

The conditions needed to produce an organic ring-shaped molecule exhibiting a persistent magnetization are calculated from quantum and chemical considerations. Using a simplified one-particle operator model and known chemical binding energies it is concluded (a) that such a molecule would need to be very large (circa) 100 Å diameter) to be ‘stable’, (b) that synthesis would probably need to take place in a pre-existing strong magnetic field.
