The tetragonal Mn3-xPdxGa becomes compensated ferrimagnet at x = 0.7. In the compensated ferrimagnet, Mn2.3Pd0.7Ga, we observed spin reorientation and topological Hall effect due to the strong spin-orbit coupling and inversion symmetry breaking by Pd atoms. We revealed that this additional Hall behavior is attributed to non-collinear spin configuration such as magnetic skyrmions. Our observations are expected that Mn-based compensated ferrimagnets are promising and will open a new avenue toward spintronic high-density and low-power devices.
