We show that it is possible to grow epitaxial Ag/Cr(001) multilayers on MgO(001) by molecular beam epitaxy (MBE) techniques. Channeling and XRD measurements reveal that the out-of-plane lattice parameter of Ag is strongly reduced, resulting in heavily strained Ag layers. Similar to results in Fe/Cr multilayers we observe in Ag/Cr multilayers an enhancement of the chromium Neel temperature. Using perturbed angular correlation (PAC) spectroscopy we see a spin density wave (SDW) out-of-plane magnetization in the Cr layers with thicknesses above 5.9 nm and definitely different spectra for thinner Cr layers.
