    • Effect of band filling in the Kondo lattice : a mean-field approach 

      Ruppenthal, Alaor Ricardo; Iglesias, Jose Roberto; Gusmao, Miguel Angelo Cavalheiro (1999) [Artículo de periódico]
      The usual Kondo lattice, including an antiferromagnetic exchange interaction between nearest-neighboring localized spins, is treated here in a mean-field scheme that introduces two mean-field parameters: one associated ...
