Building Molecular Minerals:All Ferric Pieces of Molecular Magnetite

摘要

Currently,there is a great deal of interest in the synthesis of transition-metal clusters that can behave as single-molecule magnets (SMMs).'11 An SMM requires effectively a combination of large spin ground* state with a negative zero-field splitting (D value),which leads to magnetic bistability (hysteresis) that is the property of an individual molecule.
