 note = {The high-resolution soft x-ray photoelectron study of Heusler(L2_1)-type (Fe_{2/3}V_{1/3})_{100−y}Al_y (y=23.8−25.8) alloys directly confirms the correlation between their thermoelectric properties and the electronic structures near the Fermi level. It shows the rigid-band-like shift of the main 3d bands and the increase of the photoelectron intensity at the Fermi edge with the small deviation of the Al content from stoichiometry, i.e., y=25.0. This implies the existence of the pseudogap across the Fermi level in Fe_2VAl. The Seebeck coefficients evaluated from the present spectroscopic data agree well with the experimental ones as well as the values estimated from a theoretical density of states in a rigid-band model, while the shift is much smaller than what is expected in the rigid-band model. The small modification of the electronic structure in the offstoichiometric (Fe_{2/3}V_{1/3})_{100−y}Al_y alloys may be attributed to the lower contribution of Al to the electronic states near E_F.},
