- Altermagnets are a promising class of materials for spintronic applications. However, compounds that simultaneously combine the symmetry required to support an anomalous Hall effect with good metallic conductivity and magnetic ordering temperatures well above room temperature remain elusive. Here, we demonstrate that partial substitution of Cr by Mn in epitaxial CrSb(100) thin films provides a viable route to engineer the combined structural and magnetic symmetry necessary to enable an otherwise symmetry-forbidden anomalous Hall effect. By systematically exploring the magnetic phase diagram Cr$_{1-x}$Mn$_{x}$Sb thin films, we identify a pronounced anomalous Hall effect in Cr$_{0.75}$Mn$_{0.25}$Sb. Guided by Landau theory, we model the field-driven reorientation of the Néel vector and the resulting anomalous Hall response, achieving good qualitative agreement with the experimental observations.
