X-ray scattering and absorption studies of epitaxial strains in Co-Au superlattices
نویسندگان
چکیده
X-ray scattering and EXAFS are used to probe epitaxial strain in C o A u superlattices grown by molecular beam epitaxy. We observe a thickness-dependent strain in ultrathin cobalt layers and find that tensile strains near misfit dislocations may be larger than in the more coherent interior of the Co layers. A strong enhancement of the magnetic absorption spectrum is observed in the superlattice samples.

X-ray scattering and absorption studies of MnAs/GaAs heterostructures
Ferromagnetic MnAs thin films grown on GaAs ~001! substrates by molecular-beam epitaxy have been studied by the methods of grazing incidence x-ray scattering, x-ray diffraction, and extended x-ray-absorption fine structure. Microstructures in two films prepared with different first-layer growth conditions ~template effects! are compared in terms of the interfacial roughness in the layer structu...
متن کاملReciprocal Space Mapping and Reflectivity Investigations of Epi-Ready InP Substrate
InP single crystals are used to the growth of three-component epitaxial layers and superlattices. Triple crystal X-ray diffractometry and reflectometry have been used to determine defects in InP epi-ready wafers caused by the mechanical treatment. Reciprocal space maps around 400 lattice points were separately made for mechanically polished wafers before and after etching treatment. The lattice...

hcp(101̄0) Co/Re superlattices were grown via magnetron sputtering on Al2O3(112̄0) substrates. The thickness of the Co layers was approximately 1.8 nm with the Re layer thickness varying between 0.5 nm and 3.0 nm. Low angle x-ray reflectivity revealed that for our growth conditions the interfacial roughness is approximately 0.4 nm in each material at each interface. High angle x-ray diffraction, ...
متن کاملEpitaxial strain, metastable structure, and magnetic anisotropy in Co-based superlattices (invited)
We explore the relationship between interface structure and magnetic anisotropy in three types of Co-based superlattices: Cohcp-AU; Cofcc-Cu; and CohcP-Cr, grown epitaxially on GaAs( 110). For very thin layers of Co, Co-Au, and Co-Cu superlattices exhibit a perpendicular easy axis due to magnetoelastic contributions to the anisotropy energy. The magnetic anisotropy in Co-Cr is found to be stron...
