摘要: The effect of quantum well states on the magnetic anisotropy Co films grown vicinal Cu(001) substrates was studied by in situ magneto-optic Kerr a temperature range 5 K to 365 K. uniaxial is found oscillate as function thickness with period 2.3 atomic layers, modulated exactly theoretically predicted L. Szunyogh et al. [Phys. Rev. B 56, 14036 (1997)] and independently M. Cinal [J. Phys. Condens. Matter 15, 29 (2003)] A. Umerski 73, 184423 (2006)]. Sub-monolayer Au coverage used fine-tune provide convenient experimental access oscillations. oscillations, which are present up room temperature, attributed minority $d$ band at Fermi level Co.
