    • Our experimental finding appear to be rather contradictory to the claims of G. Fabricius et al, Phys. Rev. B 55 (1997) 164, They performed the local density approximation calculation on the electronic structure of SrHfO3 and suggested a stronger hybridization for SrTiO3 than for SrHfO3 on basis of the calculated result that the Ti 3d component of the density of states in the valence region is greater than the Hf 5d component. Also, they claimed that the effect of greater Ti 3d-O 2p covalency than for Hf may be attributed to the much smaller binding energy of d orbitals in Hf (8.14 eV) than Ti 11.04 eV
