We predict a large anomalous Nernst effect in the inverse Heusler compensated ferrimagnets Ti2MnX (X=Al, Ga, and In) with vanishing net magnetic moments. Though the net magnetic moment is zero, the Weyl points in these systems lead to a large anomalous Nernst conductivity (ANC) due to the lack of a global time-reversal symmetry operation that inverts the sign of the Berry curvature. In comparison to the noncollinear antiferromagnets Mn3Sn and Mn3Ge, the high ANC stems almost entirely from the Weyl points in this class of compounds, and thus it is topologically protected. This work shows a large ANC with zero net magnetic moments in collinear systems, which is helpful for a comprehensive understanding of the thermoelectric effect in zero-moment magnetic materials and its further applications.
