Pure and random-field quantum criticality in the dipolar Ising model: Theory of Mn12 acetates
/ Authors
/ Abstract
A theoretical model for the $Mn_{12}$ 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
