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