We observe the anomalous Nernst effect (ANE) in an n-type (In,Fe)Sb ferromagnetic semiconductor (FMS) thin film with high T_C ~ 460 K, which shows a large transerve thermopower = –3.2 μV/K at 332 K and –1.3 μV/K at 447 K. The ANE in (In,Fe)Sb at room temperature is remarkebly large and comparable to those observed in Mn₃Sn and Co₂MnGa topological materials.
