Description

technical field [0001] The invention relates to magnetic materials, in particular to a zero-dimensional pyridine ligand manganese metal magnetic complex and a preparation method thereof, in particular to a terpyridine ligand manganese metal complex single-molecule magnet and a preparation method thereof. Background technique [0002] The function of energy conversion, storage or changing the energy state of magnetic materials makes magnetic materials become important basic functional materials in the electronics industry. Single-molecule magnets, a special kind of organometallic compound that can be used to store information, are obviously much smaller than conventional magnets, which means that storage devices made from such magnets have stronger data Storage capacity. In recent years, as an emerging physical and chemical interdisciplinary subject, molecular magnets have quickly become a research hotspot due to their unique properties. [0003] As a potential application o...
