Energy states of the single-molecule magnet accounting quadrupole moment at the SU(3) coherent states approach
In this paper energy states of the single-molecule magnet are calculated under the consideration of a quadrupole magnetic moment using SU(3) coherent states approach, the relief of the energy surface depending on values of parameters of single-ion anisotropy, i. e. spin and quadruple exchange, and also the parameters of quadruple dynamics is studied.
