Abstract

The invention belongs to the technical field of preparation of novel chemical materials and particularly relates to a ferromagnetic organic-inorganic hybrid nine-nucleus manganese-substituted sandwich antimoniotungstate having a spin glass behavior. The chemical formula of the antimoniotungstate is [Na(H2O)6]<2>H<4>[Mn(H2O)3]<2>{Mn<7>(H2O)<8>(C2O4)<3>[B-alpha-SbW9O<33>]<2>}.27H2O. The compound is prepared by reacting MnCl<2>.4H2O, oxalic acid, and an antimoniotungstate precursor that is Na<9>[B-alpha-SbW9O<33>].19.5H2O in an aqueous solution, is a ferromagnetic material having the spin glass behavior, can be adopted as a novel magnetic recording material, and has a good application prospect in the field of magnetic materials. A preparing method is simple, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of preparation of new chemical materials, in particular to a ferromagnetic organic-inorganic hybrid nona-nuclear manganese substituted sandwich type antimony tungstate with spin glass behavior and its preparation method and application. Background technique [0002] Molecular-based magnetic materials have become magnetic due to their advantages such as high magnetic capacity, low magnetic loss, large specific surface area, short response time, and easy synthesis, as well as applications such as temperature sensors, active components of various molecular devices, and information storage and retrieval devices. A research hotspot in the field of materials, it plays an increasingly important role in the rapid development of information technology and the progress of human society (D. Gatteschi, O. Kahn, J. S. Miller, Molecular Magnetic Materials , ATOASI series, Kluwer, Dordrecht, 1991; E. Ruiz, T. Cauchy, J. Ca...
