Problems solved by technology

Although this method can make the nanowires become multi-element alloy nanowires, due to the alternate deposition, the composition of the nanowires is not uniform, and Sm-Co and Fe-Co are distributed in segments in the nanowires, which affects the improvement of the properties of the film.

Abstract

The invention discloses a preparation method for a Tb-Fe-Co ternary rare earth alloy magnetic nano-wire film. The method comprises the following steps: preparing a Tb-Fe-Co nano-wire film in an aqueous solution by utilizing an electrochemical deposition method; adding glycine into a Tb-Fe-Co solution system, so that the glycine and Tb form a complex compound; and enabling reducing potential to move positively, simultaneously, increasing a pH value, weakening a hydrogen evolution reaction, so that Tb<3+> is reduced from the solution. The preparation method is simple in process, low in cost and high in success rate; and the compositions of an alloy deposition film are regulated by controlling the proportions of electrolyte compositions and deposition process conditions.

Description

technical field [0001] The technical scheme of the invention relates to the manufacture of a multi-element rare earth alloy magnetic nanowire film, specifically a preparation method for a Tb-Fe-Co ternary rare earth alloy magnetic nanowire film. Background technique [0002] In the contemporary technological revolution based on information, energy, and materials, information recording materials play a pivotal role. Among the materials of erasable and repeatable recording media, magnetic recording media and magneto-optical recording media are the most widely used materials. Magneto-optical storage material is a carrier material that utilizes the Kerr magneto-optical effect to record, rewrite, and delete information by magnetic writing and optical reading. It combines the advantages of optical storage and magnetic storage, and has been widely used in national management, military, aerospace, petroleum, mining, transportation and other fields that require real-time collection,...
