    Abstract

    A theoretical model for the Mn12 acetates is derived including a "random-field" effect arising from isomer effects in some families of host acetate materials. Estimates for the important energy scales are given. Phase boundaries are determined using a mean-field approximation. Predictions for experiment are presented
