On the non-equivalence of random-field ferromagnets and site-disordered antiferromagnets: fluctuations
Description
It is shown that fluctuations of the order parameter in the Curie-Weiss versions of the dilute antiferromagnet and of the Ising model with random magnetic field are not equivalent under the mapping which establishes their thermodynamical equivalence. (author)
