Role of Discommensurations in the Magnetism of Charge-Stripe Ordered La2-xSrxNiO4
In hole doped layered metal oxides there is a tendency for the charges to line up into semi-regularly spaced lines, charge-stripes. For charge-stripes that are pinned to the metal and/or oxygen sites the periodicity of charge-stripes needs to vary around the average periodicity for all but a few special commensurate doping levels. The variations in periodicity are called discommensurations. The role of charge-stripe discommensurations is now disputed in the charge-stripe ordered nickelates, along with a dispute on the possibility of significant inter-layer spin coupling. A resolution of the role of discommensurations in the magnetism of charge ordered phases of the nickelates is of great importance to aid our understanding of the role of charge order in high temperature cuprate superconductivity. This proposal will resolve the role of discommensurations in the magnetism of charge-stripe ordered La2-xSrxNiO4.
