Magnetic behaviour of Gd and Tb adlayers on Fe and Ni surfaces studied by spin polarized auger spectroscopy

Magnetic Properties of Thin Ferromagnetic Semiconducting Films

“…In the case I s = 0.2I b and t s 0X5t b (Fig. 3) the thermal variation of M expresses for m 1 a linear dependence in the temperature C , as observed in many semi-infinite FMS-ing systems both theoretically [27] and experimentally [28].…”

Theory of surface spin waves in ferromagnetic semiconductors

“…With increasing of the surface hopping term t s (t s Ͼt b ) s decreases. For small t s values (t s Ͻt b ) we obtain a linear temperature dependence of s in agreement with the experimental data of Paul et al 19 For I s ϭ2I b the behavior of s is complicated. For t s Ͼt b ͑Fig.…”

On the Theory of Thin Ferroelectric Films

“…In the case W s ¼ 2W b (Fig. 3) the thermal variation of hS z i shows for m ¼ 1 a linear dependence in the temperature region near T c , as observed in many semi-infinite ferromagnetic systems, both theoretically [21] and experimentally [22]. The critical temperature decreases due to the presence of a surface transverse field.…”
