    Notes: The magnetic and structural properties were investigated for the 2 ML Co/Cu(100) films grown at various temperatures from 125 to 350 K. By precisely controlling the film thickness, the influence of thickness on Curie temperature (TC) due to the finite size effect can be excluded. The Curie temperature of the 2 ML Co keeps almost invariant for the growth temperature (Tg) below 250 K, and drops drastically at Tg higher than 275 K. For Tg=340 K, TC dropped to 170 K which is only about half of 325 K for Tg=125 K. Accompanied with the increase of TC for the films grown at lower temperatures, the remanent Kerr signal as well as coercivity were enhanced. According to a simple theoretical estimation, the change of TC due to the variation of the magnetization and anisotropy was found to be consistent with the experimental results. The enhancement in TC or magnetization and anisotropy with various Tg should be traced back to the presence of island growth in the films grown at lower temperatures. © 2001 American Institute of Physics.
