The microwires with diameters ranging from 20 to 50 μm were extracted by the edge of a high-velocity rotating Copper wheel in purified argon. A uniform and continuous wire with 26 mm length (the effective length is around 22 mm in practical measurement) was chosen and post-processed by ADA method, which undergoes several annealing units (ranging from 40 to 120 mA for 600 s, as shown in Fig.
