Strain and Structure Driven Complex Magnetic Ordering of a CoO Overlayer on Ir(100)

Category: Scientific Highlights

PUBLISHED IN "PHYSICAL REVIEW LETTERS (PRL)"

We investigate the magnetic ordering in the ultrathin c(10×2) CoO(111) film supported on Ir(100) on the basis of ab initio calculations. We find a close relationship between the local structural properties of the oxide film and the induced magnetic order, leading to alternating ferromagnetically and antiferromagnetically ordered segments. While the local magnetic order is directly related to the geometric position of the Co atoms, the mismatch between the CoO film and the Ir substrate leads to a complex long-range order of the oxide.
