“…During the film deposition, a magnetic field of about 300 Oe was applied along the film surface to induce a uniaxial anisotropy. Then, the films were annealed at 450 °C for 30 min to improve the AMR ratio and reduce the noise . During the annealing process, a magnetic field of ∼700 Oe was applied along the easy axis to ensure the uniform magnetization reversal of magnetic domains.…”

“…Then, the films were annealed at 450 °C for 30 min to improve the AMR ratio and reduce the noise. 35 During the annealing process, a magnetic field of ∼700 Oe was applied along the easy axis to ensure the uniform magnetization reversal of magnetic domains. The background vacuum before the film deposition and annealing is better than 3 × 10 −5 Pa.…”

“…Recent tremendous studies in condensed matter physics have uncovered various exotic quantum phases with nontrivial topology in the electronic band structure. The Weyl semimetal presents a monopole-type structure of the Berry curvature, which results in rich physical phenomena. Moreover, antiferromagnets have garnered extensive interest in the spintronics community as one of the active materials for next-generation spintronic devices, with the prospect of supplying high-density memory integration and ultrafast data processing. Therefore, a kagome antiferromagnetic (AFM) Weyl semimetal such as Mn 3 Sn, which combines the above two vital advantages, can provide a versatile platform to explore the multifaceted physics of the interplay between topology and magnetism, as well as the emerging topological AFM spintronics and its multifield (magnetic, optical, and electrical fields) manipulations.…”

“…Anisotropic magnetoresistive (AMR) sensors [1] are widely used in geomagnetic navigation [2][3][4], vehicle detection [5][6][7][8] and intelligent manufacturing [9] for its high sensitivity and contactless displacement measurement [10,11]. In real applications, the magnetoresistive strips in AMR sensors usually have large length-width ratio of over 20 [12][13][14][15][16], which can significantly affect the magnetoresistive responses.…”
