    • Phase diagram for the Anderson lattice model 

      Bernhard, Ben Hur; Lacroix, Claudine; Iglesias, Jose Roberto; Coqblin, Bernard (2000) [Artigo de periódico]
      We study the competition between the Kondo effect and the Ruderman-Kittel-Kasuya-Yosida interaction in the framework of the Anderson lattice model with an extra intersite exchange term. By using an approximation based on ...

    • Spin-glass freezing in Kondo-lattice compounds 

      Theumann, Alba Graciela Rivas de; Coqblin, Bernard; Magalhães, Sergio Garcia; Schmidt, Alex Andre (2001) [Artigo de periódico]
      A theory is presented that describes a spin-glass phase at finite temperatures in Kondo-lattice systems with an additional Ruderman–Kittel–Kasuya–Yosida interaction represented by long range, random couplings among localized ...
