We clarify the physical origin of anomalies in transverse resistivity often observed in exotic materials, such as ${\mathrm{SrRuO}}_3$, in which the Berry curvature is manifested in the transport properties. The previously attributed mechanism for the anomalies, the topological Hall effect (THE) [e.g., J. Matsuno et al., Sci. Adv. 2, e160030 (2016)], is refuted by our thorough investigations as well as formulation of a model considering inhomogeneous magnetoelectric properties in the material. Our analyses fully explain every feature of the anomalies without resorting to the THE. The present results establish a fundamental understanding, which was previously overlooked, of magnetotransport properties in such exotic materials.
