Vanishing Neel Ordering of SU(n) Heisenberg Model in Three Dimensions
Noboru Fukushima
The SU(n) Heisenberg model represented by exchange operators is studied by means of high-temperature series expansion in three dimensions, where n is an arbitrary positive integer.…
Exchange constants and spin dynamics in Mn12-acetate
A. Honecker, N. Fukushima, B. Normand +2
We have obtained new inelastic neutron scattering (INS) data for the molecular magnet Mn12-acetate which exhibit at least six magnetic peaks in the energy range 5-35 meV. These are…
Exchange Interactions and High-Energy Spin States in Mn_12-acetate
G. Chaboussant, A. Sieber, S. Ochsenbein +5
We perform inelastic neutron scattering measurements on the molecular nanomagnet Mn_12-acetate to measure the excitation spectrum up to 45meV (500K). We isolate magnetic excitation…
Thermodynamic properties of ferromagnetic mixed-spin chain systems
Noboru Fukushima, Andreas Honecker, Stefan Wessel +1
Using a combination of high-temperature series expansion, exact diagonalization and quantum Monte Carlo, we perform a complementary analysis of the thermodynamic properties of quas…
