| Abstract: | We study spin-one Heiseibergm odel with single-yon anisotropy for both easy-axis and easy-plane cases. Critical temperatures are obtained for different 3-dimensional lattices. Choice of trial action S0 is discussed. |
| Keywords: | single-ion anisotropy VCE Heisenberg model critical temperature |
