This effort deals with the effort to develop idealized                          magnetic-semiconductor layered structures.  At the Naval Research               Laboratory the technique of molecular bean epitaxy will be deployed in          evaporating single crystal iron films on substrates of Ga1-xInxAs.  For         this combination of materials the lattice constant mismatch between             substrate and film is zero or relatively small.  For these growth               conditions magnetic interfacial effects as manifested in microwave              measurements depend solely on intrinsic magnetic surfaces processes.            In particular the PI may be able for the first time to measure the              intrinsic uniaxial magnetic surface anisotropy parameter in iron.               Besides this parameter, other instrinsic magnetic parameters (magnetic          relaxation, exchange-stiffness constant, cubic magnetic anisotropy...)          will be measured.  These measurements will be compared with well known          theories.  Physical understanding of intrinsic interfacial effects in           idealized magnetic-semiconductor layers should form a strong basis in           producing new artificial multilayered structures, such as magnetic              superlattices.
