Tetrakis(phthalocyaninato) rare-earth-cadmium-rare-earth quadruple-decker sandwich SMMs: suppression of QTM by long-distance f-f interactions

Abstract

Long-distance f-f interactions: Systematic and comparative studies of the magnetic properties of a series of isostructural sandwich-type tetrakis(phthalocyaninato) diterbium and monoterbium quadruple-decker complexes clearly reveal the suppression of the quantum tunneling of magnetization by the long-distance intramolecular f-f interactions (see figure).
