“…The values of B γ,2 for the Ho/Tm SL's are positive at high temperatures and very close to the Ho/Lu ones, showing a broad peak at around 80-90 K. Below 80 K, B γ,2 start to decrease, reaching a maximum slope on decreasing the temperature at − ∼ 60 K, and undergoing a change of sign at a certain temperature, which is 60 K for Ho 8 16 , where the basal-plane anisotropy of holmium blocks dominates the B γ,2 MEL stress, making the values more positive for this SL, where the thickness of holmium layers is high enough with respect to the thulium ones. This is in good agreement with the magnetization results too [44].…”

“…However, the intrinsic magnetoelastic behavior of thin-film samples had not been compared with that of crystalline bulk materials due to the lack of REFe 2 single-crystal films. The recent success in growing by MBE high quality epitaxial films of these Laves phase magnets [16] has opened the possibility of perform such kind of studies [17,18]. In this article we present magnetoelastic stress measurements performed in a series of TbFe 2 /YFe 2 (110) single-crystal bilayers.…”

Magnetoelastic stress (MS) measurements (by using a cantilever capacitive technique) within a wide range of temperatures (10-300 K) and magnetic fields (up to 12 T) have been performed. We derive expressions relating the cantilever curvatures and the magnetoelastic stresses in anisotropic thin films and SL's (for cubic symmetry) deposited onto crystalline substrates. The magnetoelastic energy associated to the interfaces and the epitaxial stress dependence of the volume MS has been investigated by studying the basal plane MS in Ho n /Lu 15 and in Ho 10 /Y m SL's: we obtain interface MS even higher than the volume ones and the effect in bulk's MS of the epitaxial strain is large. In Dy/Y and Er/Lu SL's we also deduce the MS contributions but, for Er/Lu, incomplete saturation leads to inconclusive results. Although the latter case also happens in Ho/Tm SL's, MS clearly shows anisotropy competition. In TbFe 2 (t)/YFe 2 (1000 A°) (300 A° < t < 1300 A°) epitaxial bilayers, we determine all the MS allowed by the symmetry and show that epitaxial stress strongly modifies the tetragonal MS. The thermal dependence of MS parameters is also analysed. PACS: 75.70.-i, 75.80.+q

Abstract.Magnetization loops for (110) MBE grown ErFe 2 /YFe 2 multilayer films are presented and discussed. The magnetocrystalline easy axis for the Er layers is parallel to a <111> type crystal axis, with the out of plane <111> axes favoured by the strain. For fields applied along the (110) crystal growth axis, out-of-plane magnetic exchange springs are set up in the magnetically soft YFe 2 layers. For multilayer films that display exchange spring dominated reversal at low temperatures, there is a cross-over temperature above which there are additional transitions at high fields. These features are interpreted using micro-magnetic modelling. At sufficiently high fields, applied perpendicular to the multilayer film plane, the energy is minimized by an exchange spring driven multilayer spin flop. In this state, the average magnetization of the ErFe 2 layers switches into a nominally hard in-plane <111> axis, perpendicular to the applied field.
