We have studied the epitaxial growth and structural properties of single crystal Mn/ Ag multilayers grown on (001) GaAs substrates using transmission electron microscopy. A buffer layer of Ag (001) was grown on a 5 monolayer Fe seed layer on the (001) GaAs substrate before the growth of the multilayers to obtain good quality films. Mn/Ag multilayers show very sharp and coherent interfaces for Mn layer thicknesses up to ≈ 14 monolayers. The structure of Mn in Mn/Ag multilayers depends on the thickness of the Mn layer. An fee precursor structure of Mn is proposed with a lattice parameter of 3.94Â and is expected to be antiferromagnetic.
