Description

technical field [0001] The invention relates to the technical field of new electronic materials, in particular to a preparation method of a mixed manganese cluster molecular-based magnetic material. Background technique [0002] Since 1963, Mclonnel proposed that organic compounds may have ferromagnetism, and gave the mechanism of intermolecular ferromagnetic exchange coupling. Since Wickmann synthesized the first molecular ferromagnet in Bell Laboratories in 1967, molecular-based magnets have Its unique properties quickly became a research hotspot, and thus opened the prelude to the study of molecular-based magnetic materials. In recent years, under the impetus of materials science and life science, the interdisciplinary molecular magnetism, which takes the magnetic properties of molecules containing unpaired electrons and their molecular aggregates as the research object, has entered a new period of vigorous development and has become a leapfrogging field. One of the most...
