抄録
The electrical resistivity ρ and thermopower S of Heusler compounds Fe3−xVxAl have been measured at the temperature range from 1.5 to 300 K at magnetic fields up to 15 T. The measurements of ρ and S in the high temperature range up to 800 K have been performed. ρ and S show a semiconducting behavior at high temperatures, and the obtained experimental energy gap increases almost linearly with increasing V concentration x. S is positive for x<1.0 and negative for x≥1.0 at all measured temperatures, indicating a drastic change of major carriers at x=1.0. The electron scattering due to the magnetic fluctuations of Fe clusters has a dominant effect on the behavior of ρ of the magnetic compounds at low temperatures. On the other hand, S is not sensitive to the magnetic state and the external magnetic field, which is related to the energy dependence of magnetic scattering at the Fermi level.
