Abstract
A very simple definition of Ising clusters was introduced by Rieger which joins spins with an
average individual magnetization opposite to the global magnetization. Involving percolation
methods we get very good agreements between the critical temperatures and the percolation
thresholds of diluted and undiluted Ising systems in various dimensions.
