摘要：

Ising lattices with +/- J interactions and uniform magnetic field are calculated looking for energy, magnetization and correlations at zero temperature. All magnitudes present discontinuities that occur at rational numbers for the magnetic field measured in units of J. We interpret this as a manifestation of pinning due to the complex topology of these lattices. (C) 1998 Elsevier Science B.V. All rights reserved.
