Spin-split states in aromatic molecules (pdf)

Mod. Phys. Lett. B4, 739 (1990)

A state where spin currents exist in the absence of external fields has recently been proposed to describe the low-temperature phase of Chromium. It is proposed here that such a state may also describe the ground state of aromatic molecules. It is argued that this point of view provides a more natural explanation for the large diamagnetic susceptibilities and NMR shifts observed in these molecules than the conventional viewpoint. Our model suggests a new memory mechanism.
