Further, it demonstrates that the amplitude ratio of magnetic moments at neighboring nickel sites can be accurately determined by RXS in combination with a correlated double cluster model, and controlled experimentally through structural pinning of the oxygen positions in the crystal lattice. The two key outcomes of the thesis are: (a) demonstratingfull control over the charge/bond and spin order parameters in specifically designed praseodymium nickelate heterostructures and observation of a novel spin density wave phase in absence of the charge/bond order parameter, which confirms theoretical predictions of a spin density wave phase driven by spatial confinement of the conduction electrons; and (b) assessing the thickness-induced crossover between collinear and non-collinear spin structures in neodymium nickelate slabs, which is correctly predicted by drawing on density functional theory. .Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053SuperconductivitySuperconductorsSpectroscopyMicroscopySurfaces (Physics)Interfaces (Physical sciences)Thin filmsMaterials scienceStrongly Correlated Systems, Superconductivityhttps://scigraph.springernature.com/ontologies/product-market-codes/P25064Spectroscopy and Microscopyhttps://scigraph.springernature.com/ontologies/product-market-codes/P31090Surface and Interface Science, Thin Filmshttps://scigraph.springernature.com/ontologies/product-market-codes/P25160Characterization and Evaluation of Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z17000Superconductivity.Superconductors.Spectroscopy.Microscopy.Surfaces (Physics).Interfaces (Physical sciences).Thin films.Materials science.Strongly Correlated Systems, Superconductivity.Spectroscopy and Microscopy.Surface and Interface Science, Thin Films.Characterization and Evaluation of Materials.621.38152Hepting Matthiasauthttp://id.loc.gov/vocabulary/relators/aut823587MiAaPQMiAaPQMiAaPQBOOK9910254582303321Ordering Phenomena in Rare-Earth Nickelate Heterostructures1832678UNINA
