Abstract

It is demonstrated via a numerical experiment (a Monte Carlo simulation) in the context of three-dimensional site-diluted Heisenberg spin systems that a functional dependence of the Binder ratio (V₄) on the order parameter correlation length (ξ/ L) requires a modification to the usual definition of V₄ in disordered systems. An appropriate disorder averaging procedure is proposed.
