“…The derived bulk exchange interaction constants all consistently fall in the range expected for the bulk exchange interaction of Ni [3,7,13]. The interlayer coupling strength depend on the Ni thickness in the structure, the saturation magnetization (M S ) of the layers and their respective fields ( 4…”

“…Several experimental and theoretical studies were carried out to understand the origin of the various interactions existing in this kind of systems, in particular in the interface since it presents magnetic properties different those of bulk [1][2][3][4]. Since multilayers are inherently metastable material on a nanometer scale, the introduction of the period, the number of layers and the relative thicknesses of the magnetic layers and nonmagnetic layers in multilayers will result in many interesting properties, which are sensitive to the microstructures [5][6][7][8]. The properties of these materials are mostly governed by the surface properties and hence the interface plays an important role.…”

The magnetic properties of Ni/Cu multilayers, prepared by the electron beam evaporation method under ultra high vacuum conditions, have been systematically studied by magnetic measurements. The temperature dependence of the spontaneous magnetization M (T) is well described by a T3/2 law. A spin wave theory has been used to explain the magnetization versus temperature. Based on this theory, the approximate values for the exchange interactions have been obtained

If we compare the two insertion layers magnetization-wise, it is important to note that the repetition number of [Co(t Co )/Ni(0.4)/Pt(0.6)] 4 is lower than that of [Co(t Co )/Ni(0.4)/Pd(0.6)] 9 .…”

In this study, the influence of Pd and Pt insertion layers in Co/Ni multilayers (MLs) on their magnetic properties, e.g. magnetic anisotropies, saturation magnetization, coercivity, magnetic domain size, and Curie temperature, is investigated. We compare three series of [Co/Ni/X] N ML systems (X = Pd, Pt, no insertion layer), varying the individual Co layer thickness as well as the repetition number N. All three systems behave very similarly for the different Co layer thicknesses. For all systems, a maximum effective magnetic anisotropy was achieved for MLs with a Co layer thickness between 0.15 nm and 0.25 nm. The transition from an out-of-plane to an in-plane system occurs at about 0.4 nm of Co. While [Co(0.2 nm)/Ni(0.4 nm)] N MLs change their preferred easy magnetization axis from out-of-plane to in-plane after 6 bilayer repetitions, insertion of Pd and Pt results in an extension of this transition beyond 15 repetitions. The maximum effective magnetic anisotropy was more than doubled from 105 kJ/m 3 for [Co/Ni] 3 to 275 and 186 kJ/m 3 for Pt and Pd, respectively. Furthermore, the insertion layers strongly reduce the initial saturation magnetization of 1100 kA/m of Co/Ni MLs and lower the Curie temperature from 720 to around 500 K.
