    • Compositional and magnetic properties of iron nitride thin films 

      Mosca Junior, Dante Homero; Dionisio, Paulo Henrique; Schreiner, Wido Herwig; Baumvol, Israel Jacob Rabin (1990) [Artigo de periódico]
      The compositional and magnetic properties of iron-nitride thin films deposited by de reactive magnetron sputtering under various nitrogen partial pressure conditions have been investigated by x-ray diffraction, Mossbauer ...

    • Epitaxial fe/cu superlattices on Si(111) 

      Schreiner, Wido Herwig; Mosca Junior, Dante Homero; Teixeira, Sergio Ribeiro; Mattoso Filho, Ney Pereira (1992) [Artigo de periódico]
      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 Mossbauer spectrometry, and ...

    • Magnetic susceptibility of fe/cu multilayers : ferromagnetic, antiferromagnetic, and spin-glass phases 

      Oliveira, A.J.A. de; Ortiz, Wilson Aires; Mosca Junior, Dante Homero; Mattoso Filho, Ney Pereira; Schreiner, Wido Herwig; Teixeira, Sergio Ribeiro (1998) [Artigo de periódico]
      In this work we present low-field magnetic measurements on multilayers of Fe 1.5 nm and Cu 1.5 nm layers, repeated 10 times, grown on Si~111! and Fe 5 nm/CaF2 40 nm/Si(111), substrates. Magnetic characteristics of a ...

    • Oscillatory interlayer exchange and magnetoresistance in Fe/Cu multilayers 

      Petroff, Frédéric; Barthelemy, Agnès; Mosca Junior, Dante Homero; Lottis, Daniel Kurt; Fert, Albert R.; Schroeder, Peter A.; Pratt Junior, W.P.; Loloee, Reza; Lequien, S. (1991) [Artigo de periódico]
      We have studied the magnetic and magnetotransport properties of Fe/Cu mu1tilayers prepared by sputtering. We find oscillations of the inter1ayer coupling as a function of the Cu thickness with the same long period as in ...

    • Structural change and heteroepitaxy induced by rapid thermal annealing of CaF/sub 2/ films on Si(111) 

      Mattoso Filho, Ney Pereira; Mosca Junior, Dante Homero; Schreiner, Wido Herwig; Mazzaro, Irineu; Teixeira, Sergio Ribeiro; Macedo, Waldemar A.A.; Martins, M.D. (1998) [Artigo de periódico]
      In this article we show that heteroepitaxial CaF2 films can be induced on Si~111! with a rapid thermal anneal. The change from preferentially oriented polycrystals to a single crystal with type- B epitaxy is visible by ...

    • The epitaxial growth of evaporated cu/caf2 bilayers on si(111) 

      Mattoso Filho, Ney Pereira; Mosca Junior, Dante Homero; Mazzaro, Irineu; Teixeira, Sergio Ribeiro; Schreiner, Wido Herwig (1995) [Artigo de periódico]
      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, ...

    • The evolution of sputtered iron nitride thin films under thermal treatment 

      Monteiro, W.A.; Schreiner, Wido Herwig; Baumvol, Israel Jacob Rabin; Dionisio, Paulo Henrique; Teixeira, Sergio Ribeiro; Mosca Junior, Dante Homero (1991) [Artigo de periódico]
      The thermal evolution of reactively sputtered iron nitride thin films has been investigated by xray diffraction, Mössbauer conversion electron spectroscopy, transmission electron microscopy, and magnetic measurementsT. he ...
