  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, a key component in spintronics, has gained significance due to emerging
theories surrounding noncoplanar chiral spin textures. This study focuses on
Mn2-xZnxSb, 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 dependences for THE suggests very different magnetic
interactions/structure for different compositions and underscores the strong
coupling between magnetism and transport in Mn2-xZnxSb. Our findings contribute
to understanding topological magnetism in centrosymmetric tetragonal lattices,
establishing Mn2-xZnxSb as a unique platform for exploring tunable transport
effects and opening avenues for further exploration in the realm of
spintronics.
