(a) Normalized pulsed-field magnetization of planar (T = 1.5 K), and chainlike  (T =0:5 K) Mn12 compunds. (b) The results of QMC simulations of the low-temperature magnetization for 3D  2D and 1D AF. The lines are the pulsed-field data scaled by the saturation field (Bc). (c) The relation between the exchange anisotropy and the ratio of critical temperature and primaryexchange energy in Q1D and Q2D antiferromagnets deduced from QMC simulations (d) Anisotropy of the g factor in the planar and (e) chainlike compounds measured using ESR at 10 K and 1.5 K, respectively.
