Depending on the mutual ratio between exchange interactions and the single-ion anisotropy, there appear six different phases in the ground state. The magnetic order of these phases together with the critical behaviour and corresponding magnetization curves are discussed in detail.2 pages, 4 figures, presented at 15th Conference of Slovak Physicists to be held in Stara Lesna on 11-14th September 2006, SlovakiaStatistical Mechanicstext
