The anomalous Nernst effect (ANE) in highly ordered Fe4N films was examined in the measurement configuration with an in-plane temperature gradient (∇Tx). The anomalous Nernst coefficient (Qs) in the case of ∇Tx || Fe4N was clearly larger than that in the case of ∇Tx || Fe4N. Note here that no reports on the Qs in Fe4N films have been presented. This anisotropic Qs (Qani) was also observed in a different configuration with an out-of-plane temperature gradient. Unlike Fe4N, pure Fe and A2-FeAl systems showed a negligible Qani. This Qani might be attributed to the specific hybridization effects between the 3d orbitals of Fe and the 2p orbitals of N.
