    • Atomic level mixing induced by Kr irradiation of FeCo/Cu multilayers 

      Graff, Ismael Leandro; Geshev, Julian Penkov; Teixeira, Sergio Ribeiro; Amaral, Livio; Traverse, Agnes (2008) [Journal article]
      The effects of Kr ion irradiation of FexCo1−x /Cu multilayers are investigated by means of magnetic and x-ray measurements. The irradiation was performed at room temperature with 600 keV of Kr, and the fluences were ranged ...

    • Negative differential magnetization for Ni nanoparticles in Al 

      Fonda, Emiliano; Teixeira, Sergio Ribeiro; Geshev, Julian Penkov; Babonneau, David; Pailloux, Frederic; Traverse, Agnes (2005) [Journal article]
      Using a layer-by-layer deposition technique, Ni thin films were sandwiched between AlOx layers in an Al matrix. By using x-ray-absorption spectroscopy, grazing incidence small-angle x-ray scattering, and highresolution ...

    • X-ray-absorption spectroscopy and x-ray diffraction in discontinuous Co/sub x/Fe/sub 1-x//Ag multilayers 

      Flores, Wladimir Hernandez; Teixeira, Sergio Ribeiro; Cunha, Joao Batista Marimon da; Alves, Maria do Carmo Martins; Tolentino, Hélio Cesar Nogueira; Traverse, Agnes (2000) [Journal article]
      This paper reports on the structural properties of CoxFe12x /Ag discontinuous multilayers with x 50, 0.3, 0.7, and 1. The evolution of the structural properties has been investigated by x-ray diffraction and x-ray-absorption ...
