Recently, the Anomalous Nernst Effect (ANE) is attractive as thermoelectric conversion. We have studied the electromotive force of the ANE in iron based sintered alloys. We prepared Fe-Al alloys with different Al concentration by using Spark Plasma Sintering (SPS) technique. The electromotive force of the ANE Syx has dramatically enhanced with increasing the ratio of Al and showed the maximum when the ratio of Al is 25%. Then we prepared Fe75X25 (X=B, Si, Ga) alloys for the comparison between the effects of different doping elements. Furthermore, to find more efficient ANE materials, we have tried to enhance the electromotive force of Fe75Al25 by adding other elements.
