      abstract     = {The anomalous Nernst effect (ANE)—the generation of a
                      transverse electric voltage by a longitudinal heat current
                      in conducting ferromagnets or antiferromagnets—is an
                      appealing approach for thermoelectric power generation in
                      spin caloritronics. The ANE in antiferromagnets is
                      particularly convenient for the fabrication of highly
                      efficient and densely integrated thermopiles as lateral
                      configurations of thermoelectric modules increase the
                      coverage of heat source without suffering from the stray
                      fields that are intrinsic to ferromagnets. In this work,
                      using first-principles calculations together with a group
                      theory analysis, we systematically investigate the
                      spin-order-dependent ANE in noncollinear antiferromagnetic
                      Mn-based antiperovskite nitrides Mn3XN(X=Ga, Zn, Ag, and
                      Ni). The ANE in Mn3XN is forbidden by symmetry in the R1
                      phase but amounts to its maximum value in the R3 phase.
                      Among all Mn3XN compounds, Mn3NiN presents the most
                      significant anomalous Nernst conductivity of 1.80AK−1m−1
                      at 200 K, which can be further enhanced if strain, electric,
                      or magnetic fields are applied. The ANE in Mn3NiN, being one
                      order of magnitude larger than that in the famous Mn3Sn, is
                      the largest one discovered in antiferromagnets so far. The
                      giant ANE in Mn3NiN originates from the sharp slope of the
                      anomalous Hall conductivity at the Fermi energy, which can
                      be understood well from the Mott relation. Our findings
                      provide a host material for realizing antiferromagnetic spin
                      caloritronics that promises exciting applications in energy
                      conversion and information processing.},
