Monte Carlo studies of slow relaxation in diluted antiferromagnets.

چکیده
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 relaxation primarily takes place in the domain walls.

On the relaxation dynamics of diluted antiferromagnets
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...
متن کاملNon-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 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 کاملBond-Dilution Effects on Two-Dimensional Spin-Gapped Heisenberg Antiferromagnets
Bond-dilution effects on spin-1/2 spin-gapped Heisenberg antiferromagnets of coupled alternating chains on a square lattice are investigated by means of the quantum Monte Carlo method. It is found that, in contrast with the site-diluted system having an infinitesimal critical concentration, the bond-diluted system has a finite critical concentration of diluted bonds, xc, above which the system ...
متن کاملDiluted antiferromagnets in a magnetic field: evidence for a spin glass phase
We have performed Monte Carlo simulations on diluted Ising antiferromagnets in the limit of high external magnetic fields B and strong dilution. The two relevant lines in the B T plane of the phase diagram, Bc(T) above which antiferromagnetic long range order is no longer stable and BCq(T) which marks the onset of hysteretic effects are determined. The random exchange-random field crossover exp...
