Abstract:

The proposed goal of this project is to obtain quantitative measurements of the microstructural, microchemical and micromagnetic properties of surfaces and interfaces of ultrathin films composed of magnetic materials deposited on non-magnetic, antiferromagnetic metal and insulating substrates. Surface microanalytic methods based on unique ultrahigh-vacuum scanning transmission electron microscopescanning electron microscope UHV-STEMSEM equipped with in-situ thin film preparation and characterization tools are being used. Magnetic characterization is performed in-situ using the surface magneto- optical Kerr effect SMOKE. Additional magnetic microstructure measurements are being conducted in a novel STEM based electron holography system where absolutely calibrated nanometer resolution magnetometry is possible. Of the proposed systems for study outlined in the original proposal, work has begun on FEAg, FeCu, FeCaF2 and FeCaF2Si half of the proposed systems
