Strains in Fe/Cr/Fe trilayers and (Fe/Cr)5/Fe multilayers epitaxied on MgO and MgO/SrTiO3

•Coherent Cr/Fe superlattices grown using MBE with an MgO buffer layer on MgO or SrTiO3.•Film structure (strain and stress) different on MgO20nm/SrTiO3 and MgO substrates.•XRD contrast in Fe/Cr superlattices notably enhanced by Fe vs Cr strain difference. Fe/Cr/Fe trilayers and multilayers are prepa...
