摘要：
The structural and magnetic properties of Fe/Au and Cr/Au monatomic multilayers with the tetragonal L1(0) ordered structure in paramagnetic, ferromagnetic, and antiferromagnetic states are studied by means of the self-consistent full-potential linearized augmented-plane-wave method. It is found that the L1(0) ordered Fe/Au monatomic multilayer has a ferromagnetic ground state with an enhanced moment of 2.76 mu(B) of Fe. On the other hand, the L1(0) ordered Cr/Au monatomic multilayer has an antiferromagnetic ground state with a large local moment 3.18 mu(B) of Cr. By total energy minimization, the lattice constants for their ground states are determined.
