    Photoemission study of the solid-state interdiffusion in hybrid Fe/ZnSe/GaAs(001) heterostructures (2001)

    Notes: We report the chemical stability of the hybrid Fe/ZnSe/GaAs heterostructure prepared by molecular-beam epitaxy. Analyses of photoemission spectra show a remarkable chemical stability of the Fe/ZnSe(001) interface up to 380 °C, where the effective disruption of the heterostructure occurs, together with the appearance of Ga atoms near the film surface. This suggests that the ZnSe/GaAs interface is surprisingly less stable than the Fe/ZnSe one. © 2001 American Institute of Physics.

    The epitaxial growth of evaporated Cu/CaF2 bilayers on Si(111) (1995)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Successful and unexpected epitaxial growth of Cu/CaF2 bilayers on hydrogen terminated Si(111) wafers by thermal evaporation is reported. The bilayers were characterized with conventional x-ray diffraction experiments, grazing angle incidence x-ray diffraction experiments, rocking curves, and χ scans. The growth mode of Cu films on CaF2 epitaxially grown on Si(111) is completely different from that of the Cu film grown directly on Si(111). © 1995 American Institute of Physics.

    Compositional and magnetic properties of iron nitride thin films (1990)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 67 (1990), S. 7514-7519 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The compositional and magnetic properties of iron-nitride thin films deposited by dc reactive magnetron sputtering under various nitrogen partial pressure conditions have been investigated by x-ray diffraction, Mössbauer and Auger electron spectroscopy as well as magnetic measurements. The x-ray diffraction patterns indicate a mixed phase composition. 57Fe Mössbauer spectroscopy shows that part of the nitrogen atoms are randomly distributed on interstitial sites with the formation of nonstoichiometric compounds. The excessive width of the Mössbauer lines indicates the degree of disorder of the different iron nitride precipitates. The nitrogen concentration as a function of depth is obtained by sputter-etched Auger electron spectroscopy. Furthermore, the ferromagnetic films show moderate saturation magnetization and coercivities at room temperature as compared with pure iron thin films.

    Epitaxial Fe/Cu superlattices on Si(111) (1992)

    ISSN: 1089-7550

    Notes: We report on the successful epitaxial growth of Fe/Cu superlattices on Si(111) wafers at room temperature. The superlattices were characterized with x-ray diffraction, conversion electron Mössbauer spectrometry, and selected area electron diffraction experiments. The epitaxial growth is crucially dependent on which element is deposited first on the bare Si(111).

    The evolution of sputtered iron nitride thin films under thermal treatment (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 69 (1991), S. 261-267

    ISSN: 1089-7550

    Topics: Physics
    Notes: The thermal evolution of reactively sputtered iron nitride thin films has been investigated by x-ray diffraction, Mössbauer conversion electron spectroscopy, transmission electron microscopy, and magnetic measurements. The results show that, independently of the original nitrogen content of the films, a similar composition of the end products after the 500 °C annealings is reached, being all composed of α-Fe plus γ'-Fe4N in a wide range of relative proportions. The magnetic characteristics, however, are different depending on the nitrogen content of the as-deposited films.

    Notes: Abstract The structure, composition, and magnetic characteristics of thin films multilayers of iron-iron nitride with high magnetic moment and very low coercive field are investigated. The present study together with previous ones that described in detail the magnetic properties lead to the establishment of certain requirements to obtain iron-iron nitride multilayers with outstanding magnetic characteristics.

    Description / Table of Contents: Résumé Le composé Cu2NiSn a été examiné par ATD, rayons X et mesures de résistance électrique. A température ambiante on n'a pas trouvé de structure correspondant à une phase unique. L'alliage se décompose par chauffage à partir de 160° en formant du cuivre et deux structures hcp. A 500° la structure Heusler est rétablie. On discute les résultats des mesures de résistance électrique à partir de la théorie de Markowitz pour des métaux désordonnés.
    Abstract: Zusammenfassung Die Verbindung Cu2NiSn wurde durch DTA, Röntgen- und elektrische Widerstandsmessungen analysiert. Keine Einphasenstruktur wurde bei Zimmertemperatur gefunden. Die Legierung zersetzt sich beim Erhitzen ab 160°, wobei Kupfer und zwei hcp-Strukturen gebildet werden. Bei 500° wird die Heusler-Struktur wieder hergestellt. Die Ergebnisse der elektrischen Widerstandsmessungen werden aufgrund der Markowitzschen Theorie für ungeordnete Metalle diskutiert.
    Notes: Abstract The compound Cu2NiSn was analyzed by DTA, X-ray and electrical resistivity measurements. No single-phase structure was found at room temperature. The alloy decomposes upon heating, starting at 160°, forming copper and two hcp structures. At 500° the Heusler structure is restored. Electrical resistivity results are discussed in terms of Markowitz's theory for disordered metals.

    Thermal evolution and stability of a tin nitride obtained by reactive sputtering (1994)

    Notes: Abstract Tin nitride obtained by reactive magnetron sputtering was annealed at several temperatures to study the thermal evolution and stability of the compound. X-ray diffraction, thermal effusion and conversion electron Mössbauer spectrometry were used to characterize the events. The nitride has different stabilities, depending on the ambient conditions under which the annealings are performed. Apparently only one crystallographic phase of the nitride is present before it disproportionates.
