An averaged dI/dV spectrum obtained on the c(2x2) Cr(001) thin film surfaces exhibits a surface state around +0.1 eV above the Fermi level. The intensity of the surface state peak in the spectra measured on (001) terraces is alternately varied whenever a monatomic step is crossed. Therefore, the shifted surface state as well as an original one on (1x1) Cr(001) surfaces has spin-polarized feature.
