Single-ion anisotropy effects on the energy spectra of spin S = 1 Heisenberg ring
چکیده انگلیسی

The energy spectra of the quantum spin S = 1 ring in the presence and absence of magnetic field are calculated. The numerical exact diagonalization technique exploiting the point-group symmetry is applied to the Heisenberg spin Hamiltonian with single-ion anisotropy modelling approximately the dodecanuclear nickel cluster Ni12(O2CMe)12(chp)12(H2O)6(THF)6. The energy-level dependence of the anisotropy parameter D is analyzed and the field-dependent level-crossing is presented.

Dodecanuclear nickel cluster Ni12. The numerical exact diagonalization technique is applied to the Heisenberg spin Hamiltonian with single-ion anisotropy, modelling approximately the dodecanuclear nickel cluster Ni12 as the quantum spin S = 1 ring. The energy-level dependence of the anisotropy parameter is analysed and the magnetic field-dependent level crossing is presented.Figure optionsDownload as PowerPoint slide
