We use a variational method to study the phase structure of the three-dimensional Z ( 3 ) spin model with nearest neighbour and next nearest couplings. The system shows a rich phase diagram. The order and location of the corresponding phase transitions in the ferromagnetic region is compared with a Monte Carlo analysis and found in good agreement with the analytical prediction. We have also found that a region where the phase transition is second order does exist.

Abstract: | We use a variational method to study the phase structure of the three-dimensional Z ( 3 ) spin model with nearest neighbour and next nearest couplings. The system shows a rich phase diagram. The order and location of the corresponding phase transitions in the ferromagnetic region is compared with a Monte Carlo analysis and found in good agreement with the analytical prediction. We have also found that a region where the phase transition is second order does exist. | |
