New Routes for Structural, Orbital, and Magnetic Control in Isovalent Oxide Superlattices within 6.1.1 Strong Correlations and Novel Quantum Phases of Matter
Abstract
This project aimed to discover novel physical phenomena in correlated ABO3 oxide superlattices by using interfacial coupling to control electronic degrees of freedom beyond the charge density, such as electronic bandwidth and orbital polarization (goals 1 - 3). The final year of the project focused on the study of interfaces in magnetic topological heterostructures (goal 4). 1. To demonstrate approaches for structural and orbital "delta-doping" as well as routes to more spatially confined electronic degree of freedom (beyond carrier density) in isovalent oxide superlattices. 2. To realize heterostructured materials with complex three-dimensional orbital ordering. 3. To develop new means to understand and control novel magnetotransport behavior arising from non-collinear spin textures, with emphasis on isovalent superlattices with spatially varying structural, orbital, and magnetic characteristics. 4. To use resonant x-ray scattering techniques in the study of magnetic topological heterostructures to provide quantitative and elementally-resolved measures of chemical intermixing, structural and magnetic roughness, and magnetization at buried interfaces with sub-nm spatial resolution.
