Abstract Spintronics, an evolving interdisciplinary field at the intersection of magnetism and electronics, explores innovative applications of electron charge and spin properties for advanced electronic devices. The topological Hall effect (THE), a key component in spintronics, has gained significance due to emerging theories surrounding noncoplanar chiral spin textures. This study focuses on Mn_2‐xZn_xSb, a material crystalizing in centrosymmetric space group with rich magnetic phases tunable by Zn contents. Through comprehensive magnetic and transport characterizations, we found that the high‐Zn (x > 0.6) samples display THE which is enhanced with decreasing temperature, while THE in the low‐Zn (x < 0.6) samples show an opposite trend. The coexistence of those distinct temperature dependencies for THE suggests very different magnetic interactions/structures for different compositions and underscores the strong coupling between magnetism and transport in Mn_2‐xZn_xSb. The findings contribute to understanding topological magnetism in centrosymmetric tetragonal lattices, establishing Mn_2‐xZn_xSb as a unique platform for exploring tunable transport effects and opening avenues for further exploration in the realm of spintronics.
