Highly anisotropic single-molecule magnets (SMMs) have attracted much interest in the field of molecular magnetism because of their spin features and potential technological applications. Additionally, a great effort has been devoted to the functionalization of such molecule-based systems which are made with ligands containing functional groups suitable to connect SMMs to junction devices or to perform their grafting on surfaces of different substrates. We have synthesized and characterized two lipoic acid-functionalized and oxime-based Mn(III) compounds, of formula [Mn(μ-O)(HN-sao)(lip)(MeOH)][Mn(μ-O)(HN-sao)(cnph)(MeOH)]}·10MeOH () and [Mn(μ-O)(HN-sao)(lip)(EtOH)]·EtOH·2HO () [HN-saoH = salicylamidoxime, lip = lipoate anion, cnph = 2-cyanophenolate anion].

A device architecture utilizing a single-molecule magnet (SMM) as a device element between two ferromagnetic electrodes may open vast opportunities to create novel molecular spintronics devices. Here, we report a method of connecting an SMM to the ferromagnetic electrodes. We utilized a nickel (Ni)-AlO -Ni magnetic tunnel junction (MTJ) with the exposed side edges as a test bed.
