摘要
Co-deposited CoPt alloy films grown by molecular beam epitaxy (MBE) on (0 0 1) MgO were shown to display various microstructures, different degrees of L1(0) long-range order (LRO) and a broad range of uniaxial magnetic anisotropies (K-u), depending on growth conditions and alloy composition. Experimental results of magneto-optic Kerr effect (MOKE) are presented here and the coercive fields of the films are discussed in terms of the structure, microstructure and K-u values.
