Transverse Field Ising Ferromagnetism in Mn${}_{12}$-acetate-MeOH

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.
