A preparation method of dysprosium single ion magnetic material

Abstract

The invention discloses a preparation method of dysprosium single ion magnetic material. dichloromethane and methanol are mixed according to the volume ratio of 1: 1.5 to obtain a mixed solvent; Dysprosium nitrate and Schiff base compound L were then added to that mixed solvent at a molar ratio of 1: 2 and stirring is performed at room temperature to react for 0.25-1h; The mixed solution is filtered through a filter membrane, and the filtrate is stationary for 1- 2 week, that dysprosium monoionic magnetic material was obtained. The method is simple and easy to operate. The obtained samples are stable in air and can be used in the fields of high density magnetic storage and quantum computer.

Description

technical field [0001] The invention relates to the technical field of molecular magnetic materials, in particular to a preparation method of a dysprosium single ion magnetic material. Background technique [0002] Different from traditional magnetic materials, molecular magnetic materials have the advantages of small size, easy control, and diversified structures. Single-molecule magnets are a class of molecules that exhibit slow magnetic relaxation behavior at the single-molecule level, which contain only one Single-molecule magnets with paramagnetic centers are called single-ion magnets. Due to their small size and quantum tunneling behavior, they have broad application prospects in high-density magnetic storage and quantum computers.

[0003] Since the first single-ion magnet bisphthalocyanine terbium [TbPc 2 ] - Since the report, people have begun extensive research on single-ion magnets. Compared with transition metal ions, rare earth ions have greater magnetic anisotropy and are favored by scientists. The most representative paramagnetic centers are dysprosium, terbium, and For erbium ions, the corresponding ligands are most commonly carbon-based, oxygen-based, nitrogen-based, and halogen-based ligands. The main research content in this field focuses on the synthesis of new single-ion magnets, the improvement of the performance of single-ion magnets, and the study of The source of anisotropy, etc., among which the synthesis of a variety of new single-ion magnets can lay a foundation for the study of improving the performance of single-ion magnets and studying the source of magnetic anisotropy, but the research process of many single-ion magnets in the prior art has complex synthesis, Disadvantages such as instability of samples in air
