Low-dimensional quantum magnetic materials have rich magnetic ground states and quantum phase transition behaviors. Their low-dimensional structure and internal electronic spin coupling could exhibit rich novel magnetic properties, which have wide application prospects in quantum storage and quantum transmission and have rapidly become the research frontier and hot topic in recent years. Because of their simple structures, one-dimensional quantum magnetic materials are the best systems to study the magnetic properties of low-dimensional quantum magnetic materials and thus have been focused on and studied first. Since the physicist Professor Haldane conjectured that one-dimensional quantum antiferromagnetic materials with integer and semi-integer spins have different quantum disordered ground states, researchers have been greatly interested in these materials, which have been continuously verified by experiments. In this paper, the preparation methods, crystal structure and magnetic properties of some one-dimensional quantum antiferromagnetic materials with different spin numbers are briefly introduced and provide some ideas and methods to experimentally synthesize more new one-dimensional quantum magnetic materials.
