On the relaxation dynamics of diluted antiferromagnets

چکیده
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 twoand 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.

Non-exponential relaxation in diluted antiferromagnets
Diluted Ising antiferromagnets in a homogenous magnetic field have a disordered phase for sufficiently large values of the field and for low temperatures. Here, the system is in a domain state with a broad size-distribution of fractal domains. We study the relaxation dynamics of this domain state after removing the external field for two and three dimensions. Using Monte Carlo simulation techni...
متن کاملDynamics of domains in diluted antiferromagnets
We investigate the dynamics of two-dimensional site-diluted Ising antiferromagnets. In an external magnetic field these highly disordered magnetic systems have a domain structure which consists of fractal domains with sizes on a broad range of length scales. We focus on the dynamics of these systems during the relaxation from a long-range ordered initial state to the disordered fractal-domain s...
متن کاملMonte Carlo studies of slow relaxation in diluted antiferromagnets.
Monte Carlo simulations of diluted Ising-type antiferromagnets in a uniform external magnetic field in three dimensions show rather strong irreversibilities in the magnetization and a slow relaxation of the remanent magnetization of the domain state. A detailed investigation of the domain state and its relaxation shows that for low temperatures domains are strongly pinned at vacancies and that ...
متن کاملNonexponential relaxation of diluted antiferromagnets.
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 / !...
متن کاملSlow Relaxation Process in Ising like Heisenberg Kagome Antiferromagnets due to Macroscopic Degeneracy in the Ordered State
We study relaxation phenomena in the macroscopically ordered state in the Ising like Heisenberg kagome antiferromagnets. In recent experiments, slow relaxation phenomena have been observed in kagome compounds. We introduce the ”weathervane loop” in order to characterize the ordered state and study the microscopic mechanism of the slow relaxation from a view point of the dynamics of the weatherv...
