Domain wall roughening in three dimensional magnets at the depinning transition
M. Jost, K. D. Usadel
Abstract
The kinetic roughening of a driven interface between three dimensional spin-up and spin-down domains in a model with non-conserved scalar order parameter and quenched disorder is studied numerically within a discrete time dynamics at zero temperature. The exponents characterizing the morphology of the interface are obtained close to the depinning-transition
