    • Rotatable anisotropy and coercivity in exchange-bias bilayers 

      Geshev, Julian Penkov; Pereira, Luis Gustavo; Schmidt, Joao Edgar (2002) [Artigo de periódico]
      A phenomenological approach for polycrystalline exchange-bias bilayers is proposed which explains the coercivity enhancement as well as its temperature and coupling strength dependences. In the model, it is assumed that ...

    • Structural modifications in FexCo1-x/Cu multilayers induced by ion irradiation 

      Graff, Ismael Leandro; Teixeira, Sergio Ribeiro; Amaral, Livio; Alves, Maria do Carmo Martins; Flores, Wladimir Hernandez (2004) [Artigo de periódico]
      The structural evolution of Fe30Co70 /Cu multilayers under ion irradiation is investigated in detail using x-ray techniques. The samples were irradiated with two different ions, 50 keV of He+ and 600 keV of Kr+, at room ...
