According to the method, the defect of low deposition rate of Sm-Co alloy nanowires, namely the Sm-Co alloy amorphous magnetic nanowire array in the prior art is overcome.

Description

technical field [0001] The technical scheme of the invention relates to an amorphous alloy with samarium cobalt as the main component, specifically a method for preparing an Sm-Co alloy amorphous magnetic nanowire array. Background technique [0002] Sm–Co alloys have better magnetic properties than transition metals and their alloys. As the most viable new nano-magnetic materials, new application growth points for Sm–Co industry are constantly emerging. In addition to high-density magnetic storage media, magnetic In addition to being widely used in the fields of fluids, household appliances and biomedicine, it has also greatly promoted the potential development of micro-devices in the computer, information and electromechanical industries. Therefore, people began to study the Sm-Co nano-magnetic materials. Since 1982, Hu Zuoqi, Zhang Yulong and others have conducted creative research on amorphous Sm–Co perpendicular magnetization films, and found that Sm–Co alloys have hig...
