We study the geometrical properties of the domain structure that results when a random Ising ferromagnet is quenched to zero temperature. We define a novel connectivity transition between like spins in the frozen configuration, and show that it is in a new universality class, distinct from that of random percolation. The scaling is robust and independent of model details. The relevance of this transition to spinodal decomposition is discussed.

Abstract

We study the geometrical properties of the domain structure that results when a random Ising ferromagnet is quenched to zero temperature. We define a novel connectivity transition between like spins in the frozen configuration, and show that it is in a new universality class, distinct from that of random percolation. The scaling is robust and independent of model details. The relevance of this transition to spinodal decomposition is discussed.
