Abstract
Existence of a phase-transition is proved for an infinite linear chain of spins μ j =±1, with an interaction energy
whereJ(n) is positive and monotone decreasing, and the sums ΣJ(n) and Σ (log logn) [n 3 J(n)]−1 both converge. In particular, as conjectured byKac andThompson, a transition exists forJ(n)=n −α when 1 < α < 2. A possible extension of these results to Heisenberg ferromagnets is discussed.
