In recent years, single molecule magnets (SMMs) have attracted much attention due to their unique properties such as quantum tunneling of magnetization (QTM) and hysteresis of pure molecular origin [1], making these materials potential candidates for future applications in ultra-high density data storage devices. Only very recently first experiments indicating the conservation of magnetic properties of SMM clusters upon surface deposition have been reported boosting the investigation of SMM monolayers [2].
We present an overview of the latest achievements in the investigation of Mn12 monolayers as well as the individual molecules by means of scanning probe techniques, synchrotron radiation based techniques, and magnetization measurements. In particular, novel approaches towards the assembly of Mn12 SMMs on substrates suited for advanced studies or possible applications are highlighted.
