Researches on ultrathin magnetic films are very important due to the applications in aspects of high-density data storage media based on the giant and tunneling magnetoresistance (MR) effect,for example,Co/Cu/Co sandwich structure.Performance of MR strongly depends on the geometric and electronic properties of the interface [1],and thereby in practical applications it is very essential to select a suitable substrate for depositing magnetic structures.
