We studied single crystals of orthorhombic Sr2VO4 containing spin-singlet dimers of V4+(3d1) and those with Ti or Nb substituted for V. We found that both Ti and Nb dopings induce the evolution of a Curie-Weiss component in the magnetic susceptibility, but the rate of evolution with doping is several times higher for Nb doping. We also found that Nb doping induces the conduction of d electrons. These results can be explained by the hybridization of the Nb 4d states with the 3d states of the neighboring V ions, possibly causing rearrangement of the d electron in the doubly degenerate e states in the V ion.
