Second-order transverse magnetic anisotropy induced by disorders in the single-molecule magnet Mn12
Kyungwha Park, Tunna Baruah, Noam Bernstein +1
For the single-molecule magnet Mn12, Cornia et al. recently proposed that solvent molecules may cause the quantum tunneling that requires a lower symmetry than S4. However, magneti…
Properties of low-lying excited manifolds in the Mn12 acetate
Kyungwha Park, Mark R. Pederson, C. Stephen Hellberg
Most experimental data on the single-molecule magnet Mn acetate have been successfully explained by the assumption that the Mn acetate has an effective ground-state s…
Electronic, magnetic, and vibrational properties of the molecular magnet Mn4 monomer and dimer
Kyungwha Park, Mark R. Pederson, Noam Bernstein
A new type of the single-molecule magnet [Mn_4 O_3 Cl_4 (O_2 CEt)_3(py)_3] forms dimers. Recent magnetic hysteresis measurements on this single-molecular magnet revealed interestin…
Low-temperature nucleation in a kinetic Ising model with soft stochastic dynamics
Kyungwha Park, Per Arne Rikvold, Gloria M. Buendia +1
We study low-temperature nucleation in kinetic Ising models by analytical and simulational methods, confirming the general result for the average metastable lifetime, <tau> = A*exp…
DFT calculation of the intermolecular exchange interaction in the magnetic Mn dimer
Kyungwha Park, Mark R. Pederson, Steven L. Richardson +2
The dimeric form of the single-molecule magnet [MnOCl(OCEt)(py)] recently revealed interesting phenomena: no quantum tunneling at zero field and tunneli…
Defects, Tunneling, and EPR Spectra of Single-Molecule Magnets
Kyungwha Park, M. A. Novotny, N. S. Dalal +5
We examine theoretically electron paramagnetic resonance (EPR) lineshapes as functions of resonance frequency, energy level, and temperature for single crystals of three different…
