Abstract

Using high-frequency EPR spectroscopy we have found that a cluster comprising eight iron(III) ions, Fe 8 , which is essentially flat, has a ground S = 10 state and an Ising-type anisotropy. For the first time both ac susceptibility and Mössbauer spectroscopy could be used in order to monitor the rel...
