Abstract

We report measurements of the magnetic susceptibility of single crystals of Mn $_{12}$ -acetate-MeOH, a new high-symmetry variant of the original single molecule magnet Mn $_{12}$ -acetate. A comparison of these data to theory and to data for the Mn $_{12}$ acetate material shows that Mn $_{12}$ -acetate-MeOH is a realization of a transverse-field Ising ferromagnet in contrast to the original Mn $_{12}$ acetate material, in which solvent disorder leads to effects attributed to random field Ising ferromagnetism.
