High Spin Preparati Synthesis, Self Assembly And Magnetic Properties Of High Spin Manganese Compounds On And Magnetic Characterization

In the 21 st century is the era of rapid development of science and technology, all kinds of materials related to the magnetic also gained extensive attention and application. Especially in recent years, the magnetic materials in defense of the people’s livelihood and social various aspects plays an indispensable role.After the darling of the magnetic material single molecular magnets, and reported the similar to the magnetic properties of single magnet. Today reported a variety of single magnet, structure also have significant differences, but still a very limited number of single magnet. According to the different magnetic coupling effect between the spin vector, single magnet can be divided into ferromagnetic type single magnet, ferrous single magnet and ferromagnetic and the ferromagnetic alternate type single magnets.Simple the first chapter of this article stated the development achievements in the process of magnetic materials, introduced the basic concept and principle of single molecule magnet and its law of developmentThe second chapter, change the traditional source of manganese manganese and manganese chloride, bromide to manganese acetate, benzoic acid and trifluoroacetic acid manganese, one dimensional chain is obtained by introducing carboxyl single magnet, and the magnetic properties were studied.The regulation of the third chapter through to the solution polarity, change the crystal growing conditions for synthesis of 2- amino- 1, 3 propanediol as the law of the ligand compounds, and greatly shortened the time of crystal growth.The fourth chapter the conclusion part summarizes the introduction of carboxyl influence on crystal structure, explore the relationship between the solution polarity and the crystal growth time...
