Nonanalytic Behavior Above the Critical Point in a Random Ising Ferromagnet
Abstract
It is shown that in a class of randomly diluted Ising ferromagnets the magnetization fails to be an analytic function of the field H at H=0 for a range of temperatures above that at which spontaneous magnetization first appears.
