Abstract
The structural and magnetic properties of (Cr, Mn, Fe)/Ag monatomic multilayers with the tetragonal L10 ordered structure in paramagnetic, ferromagnetic and three antiferromaenetic states are studied by means of the self-consistent full-potential linearized augmented-plane-wave method. By total energy minimization, the lattice constants for their ground states are estimated. It is found that the L10 ordered Cr/Ag has an AF1-type antiferromagnetic ground state kith a large local moment 3.30μB of Cr, the L10 ordered Mn/Ag has an AF2-type antiferromagnetic ground state with a large local moment 3.63μB of Mn, and the L10 ordered Fe/Ag monatomic multilayer has a ferromagnetic ground state with an enhanced moment 2.75μB of Fe.
