Abstract
Owing to extremely slow decay of correlations, the limit H --> 0 prese nts a poor approximation for the Ising model on the Sierpinski gasket. We present evidence of the competitive interplay between finite size scaling and thermodynamic scaling for this model, where both finite si ze and finite field induce an apparent phase transition, These observa tions may be relevant for the behavior of porous magnetic materials in real laboratory conditions.
