Title: The random field critical concentration in dilute antiferromagnets

Abstract

Monte Carlo techniques are used to investigate the equilibrium threshold concentration, x{sub e}, in the dilute anisotropic antiferromagnet Fe{sub x}Zn{sub 1-x}F{sub 2} in an applied magnetic field, considered to be an ideal random-field Ising model system. Above x{sub e} equilibrium behavior is observed whereas below x{sub e} metastability and domain formation dominate. Monte Carlo results agree very well with experimental data obtained using this system. (c) 2000 American Institute of Physics.
