Transverse field Ising ferromagnetism in Mn12-acetate-MeOH
نویسندگان
چکیده
We report measurements of the magnetic susceptibility of single crystals of Mn12-acetate-MeOH, a newlysynthesized high-symmetry variant of the original single molecule magnet Mn12-acetate. A comparison of these data to theory and to data for the Mn12-acetate material shows that Mn12-acetate-MeOH is a realization of a transverse-field Ising ferromagnet in contrast to the original Mn12-acetate material, in which solvent disorder leads to effects attributed to random-field Ising ferromagnetism.

Quantum fluctuations and long-range order in molecular magnets
We review our studies of the effect of transverse fields on the susceptibility and magnetization of single crystals of the prototype single molecule magnet (SMM), Mn12-acetate, and of a new high-symmetry variant, Mn12-acetate–MeOH. SMM single crystals can exhibit long range ferromagnetic order associated with intermolecular dipole interactions. Transverse fields increase quantum spin fluctuatio...
متن کاملMagnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice
Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization, internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.

In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
متن کاملIncommensurate transverse anisotropy induced by disorder and spin-orbit-vibron coupling in Mn12 acetate
It has been shown within density-functional theory that in Mn12 acetate there are effects due to disorder by solvent molecules and a coupling between vibrational and electronic degrees of freedom. We calculate the in-plane principal axes of the second-order anisotropy caused by the second effect and compare them with those of the fourth-order anisotropy due to the first effect. We find that the...
متن کاملExperimental evidence of multiple magnetic relaxation processes in Mn12 acetate and Mn12 2-Cl benzoate
The Mn cluster complexes Mn12(RCOO)16(H2O)4O12 with R = CH3 and 2ClPh (hereafter referred to as Mn12 acetate and Mn12 2-Cl benzoate, respectively) exhibit macroscopic magnetic quantum tunneling. Dynamical magnetic measurements indicate for both samples that the anisotropy energy barrier is nearly the same and that the relaxation times have sharp minima at the same resonant fields. However, we s...
