LEBRECHT, W.  e  VALDES, J. F.. Frustración en redes arquimedianas antiferromagnéticas. Rev. mex. fis. [online]. 2013, vol.59, n.6, pp.554-559. ISSN 0035-001X.

This paper tackles the problem of studying anatically the phenomena associated to magnetic frustrations for different Archimedean lattices with periodic boundary conditions, all of them in the antiferromagnetic phase. A lattice formed by N spins is considered and modeled through ±J Ising model. Antiferrogmagnetic phase is restricted to +J interactions between two near-nearest neighbor spin sites. Topological parameters such as frustrated plaquettes, frustration length and energy associated to the ground level at T=0 are reported. The relative position of a triangular interaction for each lattice is as much or more important than the coordination number for the same lattice.

Palavras-chave : Archimedean lattices; frustration; plaquettes.
