Notes:
Monte Carlo results on the three-dimensional randomly-diluted Ising antiferromagnet FexZn1−xF2 indicate that its spin-glass-like phase at x=0.25 and zero magnetic field is characterized by the presence of finite antiferromagnetic domains, separated by random vacancies, but strongly correlated in time. The glassy behavior is a consequence of the combined action of short-range interactions and the presence of strong density fluctuations in the highly diluted regime, close to the percolation concentration. By studying the aging of the system, we also find that its dynamics is much alike that of theoretical spin-glass models. © 2000 American Institute of Physics.
