摘要：

Monte Carlo techniques are used to investigate the equilibrium threshold concentration, x(e), in the dilute anisotropic antiferromagnet FexZn1-xF2 in an applied magnetic field, considered to be an ideal random-field Ising model system. Above x(e) equilibrium behavior is observed whereas below x(e) metastability and domain formation dominate. Monte Carlo results agree very well with experimental data obtained using this system.
