    • Effect of composition and short-range order on the magnetic moments of Fe in Fe/sub 1-x/V/sub x/ alloys 

      Krause, Joao Carlos; Schaf, Jacob; Costa Junior, Moacir Indio da; Paduani, Clederson (2000) [Artigo de periódico]
      We report dc magnetization, Mössbauer spectroscopy, and x-ray-diffraction measurements on Fe₁₋xVx alloys, quenched or heat treated, with single phase bcc structure in the whole concetration range. It is well known that the ...

    • Electronic structure and magnetization of Fe-Co alloys and multilayers 

      Paduani, Clederson; Krause, Joao Carlos (1999) [Artigo de periódico]
      The magnetic properties and electronic structure of bcc Fe–Co alloys and multilayers are investigated with the first-principles molecular cluster discrete variational method. The density of states and the contact interactions ...

    • Electronic structure of disordered Fe-V alloys 

      Krause, Joao Carlos; Paduani, Clederson; Schaf, Jacob; Costa Junior, Moacir Indio da (1998) [Artigo de periódico]
      The first-principles discrete variational method is employed to investigate the electronic structure and local magnetic properties of disordered Fe-V alloys. The spin-polarized case is considered in the formalism of the ...

    • Electronic structure of substitutional 3d impurities in gamma/sup'/-fe/sub 4/n 

      Krause, João Carlos; Paduani, Clederson (1997) [Artigo de periódico]
      The magnetic and electronic structure of 3d localized impurities (Sc, Ti, V, Cr, Mn, Co, Ni, Cu and Zn) in the ferromagnetic iron nitride γ - F e4N are investigated in molecular cluster calculations with the discrete ...
