“…One approach was to use more sophisticated techniques like Green's functions (GF), as done in [6][7][8][9][10][11][12]. Another direction was to study the influence of surfaces on the magnetic structure [13][14][15][16], while several studies were dedicated to the influence of anisotropy [17,18].…”

“…Applying the standard MFA procedure 26 to the rotated Hamiltonian ͑12͒ ͑for aϭ0), from the minimum of the Gibbs' free energy we obtain the expressions for the magnetizations of the layers and additional relation for the reconstruction angle (T 0, l Јϭ͗Ŝ zЈ (l)͘/S, lϭ0,1,2, . .…”

“…(4) and (5) shows that the higher temperature corresponds to the ferromagnetic ordering (s 1 ws 2 ), while the lower one to the antiferromagnetic ordering (s 1 wKs 2 ). Using the reasoning similar to the one applied in [10], one can show that FM ordering corresponds to the lower free energy, so that it is the stable phase and the system possesses a common (same for all the system) Curie temperature T C Z T C 1 . We shall comment Spirin's results [7] in the final Section and we wish to stress that we obtain the same result (unique T C !)…”
