Abstract
While the anomalous Hall effect (AHE) has been extensively studied in the past, analyzing its mechanism continues to be a critical topic in condensed matter physics, especially in unconventional magnetic materials with noncollinear or noncoplanar magnetic structures. Here, we explore the AHE in the noncoplanar magnet and identify the intrinsic mechanism as its dominant origin using a refined scaling method. Conventional scaling analysis fails in this system as it treats the magnetization as a constant, thereby misattributing its influence to scattering () and obscuring the true AHE mechanism. With the field and temperature dependence of magnetization explicitly incorporated, the proper scaling relationship is restored, allowing the exponent to be accurately determined and thus confirming the intrinsic origin. Our study provides a detailed analysis of AHE in and demonstrates that analyzing AHE mechanisms in such complex magnetic systems requires careful modifications to account for magnetization effects. Such adaptations, which account for the influence of the nonsaturated magnetic state on the Hall effect, are crucial to prevent the misinterpretation of scaling failure as the emergence of extrinsic origins, thereby ensuring the accurate extraction of the intrinsic Berry curvature contribution from the complex magnetic background.
