Heptanuclear [FeIII6Criii]3+ complexes experimentally studied by means of magnetometry, X-ray diffraction, XAS, XMCD and spin-polarized electron spectroscopy in cross-comparison with [MnIII6CrIII]3+ single-molecule magnets

Abstract

Subsequent to the similar [MnIII6CrIII ]3+ single-molecule magnets (SMM), the recently studied [FeIII6CrIII ]3+ structural type adsorbed thin films prepared on Si and gold-coated glass substrates have been experimentally studied by means of spin-polarized electron spectroscopy (SPES) and X-ray magnetic circular dichroism (XMCD) at the Fe L3,2 edge using circularly-polarized synchrotron radiation. The results are cross-compared to the corresponding data obtained from the recently published measurements with Mn-based SMM [1], also in terms of the local spin and orbital magnetic moments obtained. Furthermore, [FeIII6CrIII ]3+ single crystals have been experimentally studied by means of magnetometry and X-ray diffraction.
