摘要：

By means of an electron beam deposition technique under ultrahigh vacuum, Co/Au(001) superlattices were prepared on GaAs(001) substrates with a 500 angstrom thick Au(001) buffer layer. The superlattices were characterized by reflection high-energy electron diffraction (RHEED), and x-ray diffraction. We found that well defined single-crystalline Co/Au(001) superlattices can be obtained only for samples with Co layer thickness below about 10 angstrom. The results from x-my diffraction measurements indicate a slightly trained BCC structure for Co layers with the lattice constants a(parallel-to) = 2.88 +/- 0,01 angstrom in the film plane and a(perpendicular-to) = 2.78 +/- 0.02 angstrom along the growth direction.
