Triggering spin reversal in nanomolecules and nanoclusters on demand

Abstract Spin reversal in magnetic nanomolecules and nanoclusters is considered. A method is suggested allowing us to maintain magnetic polarization in a metastable state for a long time and, also allows us to start the reversal process at any required time. This method can find applications for the operation of storage memory devices and for the regulation of processes in spintronics.
