Abstract
We report on extensive Monte Carlo simulations of diluted Ising-type antiferromagnets in a uniform magnetic field in three dimensions. The analysis of the relaxation data of the domain state leads to a power-law decay of the remanent magnetization and internal energy. The corresponding exponents are proportional to the temperature. The power noise spectrum is investigated, showing roughly 1/f noise.
