I investigated the anomalous Nernst effect in a sample of Heusler alloy Co_2-xFe_xCrAl. The samples were prepared by the arc-melting method, and crystalline evaluation was performed by structural analysis using X-ray diffraction and composition analysis using X-ray fluorescence analysis. In addition, physical properties were measured mainly by Nernst measurement, Hall measurement, and electrical resistivity. Using the results, I discussed the anomalous contribution of the anomalous Nernst effect.
