Abstract

The invention discloses polyacid dysprosium single-molecular magnets and a preparation method of the polyacid dysprosium single-molecular magnets and belongs to the field of magnetic storage materials. The chemical formula of the single-molecular magnets is [NaDy(DOTA)2 7H2O] [Fe(CN)5NO]2 11H2O, wherein DOTA is 2,2',2'',2'''-(1,4,7,10-tetraazacyclododecane-1,4,7,10-tetra) quadrol. The preparation method of the polyacid dysprosium single-molecular magnets includes the following steps that dysprosium nitrate, DOTA and sodium nitroprusside are prepared into a solution according to the molar ratio 1:1:1, the solution is mixed at normal temperature for one hour and then filtered, filtrate stands still at normal temperature, crystals are separated out, and the crystals are the polyacid dysprosium single-molecular magnets. The polyacid dysprosium single-molecular magnets can be applied to new magnetic storage materials. The preparation method of the polyacid dysprosium single-molecular magnets is simple, easy to achieve and low in cost.

Description

technical field

[0001] The invention relates to a polydysprosium acid monomolecular magnet and a preparation method thereof, belonging to the field of magnetic storage materials. Background technique

[0002] Single-Molecule Magnets (SMMs) is a special molecular magnetic material, and its research can be regarded as a bridge between molecular electronics and spintronics. SMMs are in the nanometer range, have slow magnetic relaxation, exhibit hysteresis behavior similar to traditional magnets, and have quantum tunneling effects; a single molecule of SMM can be regarded as an ultra-small magnet and can be used to store information. In theory, each molecule could store one bit of information. SMMs are much smaller than ordinary magnets, which means stronger information storage capacity, so they show broad application prospects in the fields of ultra-dense storage and quantum computing, and have obvious huge commercial and industrial value.
