Abstract

A numerical method is used to investigate the scaling behavior of positionally random Ising and quantum Heisenberg spin 1 2 systems in two and three dimensions with short range antiferromagnetic interactions. A study of the distribution of couplings, as high-lying states of the system are eliminated, exhibits qualitatively different behavior in the two cases. This bears upon the possibility of frustration and spin-glass freezing in these systems at low temperature.
