Phase transition at finite temperature in one dimension: Adsorbate ordering in Ba/Si(111)3x2
Steven C. Erwin, C. Stephen Hellberg
We demonstrate that the Ba-induced Si(111)3x2 reconstruction is a physical realization of a one-dimensional antiferromagnetic Ising model with long-range Coulomb interactions. Mont…

Is manganese-doped diamond a ferromagnetic semiconductor?
Steven C. Erwin, C. Stephen Hellberg
We use density-functional theoretical methods to examine the recent prediction, based on a mean-field solution of the Zener model, that diamond doped by Mn (with spin S=5/2) would…

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…
