抄録	Spin dependent electronic properties of c(2x2) Cr(001) thin film surfaces grown on MgO(001) substrates are investigated by means of spin-polarized scanning tunneling microscopy and spectroscopy. 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. (C) 2006 American Institute of Physics.
