±J Ising model in 2D and of general composition
We study the effects of frustration in terms of eigenstates within the Pfaffian (or Grassman variable) formalism for the Ising system. The destruction of ferromagnetic order is due to the introduction, at a critical defect concentration, of eigenstates extended over the entire system. This effect is...
