Abstract

The magnetic structures of epitaxial Cr(001) thin films with periodic monatomic Sn or Au spacer layers, [Cr(8.0nm)/Sn(0.2nm)]×30, [Cr(4.0nm)/Sn(0.2nm)]×60 and [Cr(8.0nm)/Au(0.2 nm)]×30 multilayers, were investigated by neutron diffraction. A commensurate antiferromagnetic structure was stabilized in all these multilayers at 300 K. It was found that highly distorted sinusoidal spin density waves (SDWs) with the propagating vector normal to the film plane were formed in the multilayers with Cr(8.0 nm) at 20K. The SDW period was twice as large as that of the multilayer. The antinodes of the SDW are probably pinned at the Cr/Sn or Cr/Au interfaces so as to form SDWs with a period much longer than that of bulk Cr.
