The non-monotonic temperature dependence and sign reversal of chirality-related anomalous Hall effect in highly conductive metals are studied. Through the analysis scattering rate, we find that non-monotonicity have two major origins: (1) competition between contribution from short-range long-range spin correlations (2) correlation high field. former mechanism gives rise to a wide range electron density and, some cases, resistivity as decreases. On other hand, latter is responsible for conductivity field, which generally occurs magnets with antiferromagnetic interactions. results demonstrate how reflects local provide insights into by chirality.
