Abstract: | We study the site-bond percolation problem for clusters of holes and particles with antiferromagnetic order by means of the Bethe cluster approximation. We find that the droplets (i.e.P B =1?e ?|K|/2) diverge at the antiferromagnetic critical pointH=0,T=T c; however forH≠0 they diverge along a percolation line which is different from the Antiferromagnetic Phase Boundary except atT=0. |
