Zusammenfassung

Single-molecule magnets (SMM) of the [MnIII6CrIII]3+ structural type prepared on Si and gold-coated glass substrates have been investigated by spin-resolved electron spectroscopy (SPES) and X-ray magnetic circular dichroism (XMCD) at the Mn L3,2 edge and in addition by XMCD at the Cr L3,2 edge using synchrotron radiation. Differences between the two methods are discussed. Despite its severe limitations for 3d transition metals, a spin sum rule evaluation is nevertheless performed for the MnIII centres in the [MnIII6CrIII]3+ SMM to provide a simple means of comparing XMCD and spin-resolved electron spectroscopy results.
