• Application of the underscreened Kondo lattice model to neptunium compounds 

      Thomas, Christopher; Simões, Acirete Souza da Rosa; Iglesias, Jose Roberto; Lacroix, Claudine; Coqblin, Bernard (2012) [Artículo de periódico]
      The coexistence of Kondo e®ect and ferromagnetic order has been observed in many uranium and neptunium compounds such as UTe or Np2PdGa3. This coexistence can be described within the underscreened Anderson lattice model ...
    • Magnetic behavior of the NixFe1−xNb2O6 quasi-one-dimensional system : isolation of Ising chains by frustration 

      Sarvezuk, Paulo Willian Carvalho; Gusmao, Miguel Angelo Cavalheiro; Cunha, Joao Batista Marimon da; Isnard, Olivier (2012) [Artículo de periódico]
      Physical properties of the NixFe1−xNb2O6 compounds are investigated combining x-ray and neutron powder diffraction with magnetic and calorimetry measurements as well as 57Fe Mössbauer spectroscopy. This system is known to ...
    • Tunable asymmetric magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films 

      Silva, Edimilson Felix da; Gamino, Matheus; Andrade, Antonio Marcos Helgueira de; Corrêa, Marcio Assolin; Vázquez Villalabeitia, Manuel; Bohn, Felipe (2014) [Artículo de periódico]
      We investigate the magnetization dynamics through the magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films. We observe that the magnetoimpedance response is dependent on the thickness of the non-magnetic Cu spacer ...
