We define a class of interfaces in random exchange Ising ferromagnets that are associated with nonequilibrium states of the system. We find that the interfaces are fractal and have a fractal dimension of about 1.6. The scaling properties are reburst and characteristic of a new universality class. Our results suggest the possibility that the fractal structures observed in nature need not be related to the true equilibrium of the system.

Abstract
We define a class of interfaces in random exchange Ising ferromagnets that are associated with nonequilibrium states of the system. We find that the interfaces are fractal and have a fractal dimension of about 1.6. The scaling properties are reburst and characteristic of a new universality class. Our results suggest the possibility that the fractal structures observed in nature need not be related to the true equilibrium of the system.
