Symmetry classification based on multipoles has broadened the understanding of cross-correlated responses. In this study, we focused on the magnetic toroidal order in the antiferromagnetic phase of the ferroaxial crystal PbMn₂Ni₆Te₃O₁₈ and successfully visualized magnetic toroidal domains through directional dichroism measurements. Furthermore, we experimentally demonstrated that the reversal of ferroaxial domains corresponds to the reversal of magnetic toroidal domains, revealing the potential for observing ferroaxial domains via directional dichroism.
