Novel Hall phenomena are observed in centrosymmetric Mn5Ge3 ferromagnet. Contrary to the typical behavior observed in most ferromagnets, the large anomalous Hall effect is strongly suppressed at low temperatures, giving way to a dominant ordinary Hall effect that is well described by a two-band model. This unique temperature dependence suggests a competition between intrinsic and skew-scattering mechanisms. Furthermore, this work identifies two distinct origins of the topological Hall effect: one arising from non-collinear spin textures and the other from skyrmion bubbles. These findings offer new insights into both the anomalous and topological Hall effects.
