Abstract
The phase diagram of a diluted Ising antiferromagnet in an external magnetic field has a disordered phase for sufficiently large values of this field and for low temperatures, in which the system's equilibrium state is a domain state. We study the relaxation dynamics out of this state after switching off the magnetic field, for two- and three-dimensional diluted antiferromagnets using Monte Carlo Simulation techniques. We measure the decay of the initial magnetization carried by the domain state. The data can be described by a unique law for a wide range of temperatures, magnetic fields and dilutions in two and three dimensions.
