Abstract
A hexagonal spin nanotube is studied using the Effective Field Theory with correlations (EFT) and the differential operator technique (DOT). Each spin is connected to the nearest-neighbors through exchange couplings both along the chains (J//) and adjacent chains (Jâ¥). The effects of the exchange, the single-ion anisotropy and the magnetic field on the phase diagram and the magnetic properties have been examined. It is shown that the longitudinal and transverse exchange parameters have strong effect on the shape of the phase diagram. Some original behaviors have been emerged. In particular, when the two exchange parameters are opposite, strong frustrations occur, atypical magnetization plateaus and jumps appear.
