Abstract

A three-element CoZnFe alloy of β-Mn phase and a preparation method thereof, mixing Co powder, Zn powder and Fe powder with a purity of 99.9% according to the molar ratio of (2~4.5):(2~5):1, After 3-4 hours of full grinding, a uniformly distributed powder mixture is obtained, then vacuumized, and then sealed to keep the vacuum in the tube; put the sealed quartz glass tube with the sample into the muffle furnace for sintering , quickly heat up to 1000-1100°C at a rate of 180-200°C / h, and keep warm for 10-12h; then cool down to 925-1025°C at a rate of 1-1.5°C / h; keep warm at 925-1025°C for 70-75h; Finally, the quartz glass tube containing the alloy sample is taken out, quenched in water, and the three-element CoZnFe alloy sample is taken out. The equipment required by the present invention is simple, and the experimental conditions are easy to control.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a β-Mn phase three-element CoZnFe alloy and a preparation method thereof. Background technique [0002] In recent years, magnetic skyrmions, a novel topologically stable magnetic structure with particle properties, whose special spin alignment leads to a current density driving its state change that is 5–6 orders of magnitude lower than that driving conventional magnetic domains, Therefore, it becomes an ideal candidate material for constructing future high-density, high-speed, low-energy magnetic information storage devices. [0003] According to theoretical predictions and experimental results, there are many crystal structures with skyrmion phases, but there are only a handful of materials with non-centrosymmetric structures that have this kind of magnetic information storage, mainly concentrated in alloys with B20 structure and Multiferroic oxide material Cu 2 ...
