Abstract

The thermoelectric properties of the stoichiometric and off-stoichiometric Heusler compounds Fe2-xTi1+xSn between 10 K and 400 K were studied. The electrical resistivity and the Seebeck coefficient were found to be very sensitive to the off-stoichiometry. From the Seebeck coefficient (S) measurements it was found that all the studied materials were p-type materials with moderate S values of about 20-30 μV/K at room temperature. Broad maximums were observed at around 330 K in S for Fe2TiSn and Fe 2.05Ti0.95Sn, and the maximum was found to shift to higher temperatures with replacing more Ti or Fe.
