“…We see that the angle between the magnetic moment and the normal to sample increases with the number of the layer. This distribution is very similar to that demonstrated by thin films with different types of surface and volume anisotropy [26][27][28][29] .…”

We report a study of interlayer exchange interaction in multilayer CoPt/Co structures consisting of periodic CoPt multilayer film with an "easy axis" anisotropy and thick Co layer with an "easy plane" anisotropy separated by Pt spacer with variable thickness. The magnetooptical Kerr effect (MOKE) and ferromagnetic resonance (FMR) measurements show up the essentially non-collinear state of magnetic moments of the layers and strong exchange coupling between CoPt and Co subsystems. The estimation of effective anisotropy and exchange coupling in a simple model based on the LandauLifshitz-Gilbert equation describing magnetization dynamics was performed.

“…This refers in particular to films with perpendicular magnetic anisotropy, [1][2][3][4][5][6][7][8][9] whereas the main effect of magnetostatic interactions in films with easy-plane anisotropy is to confine the magnetization to the film plane. 10,11 To illustrate the difference, we approximate the thin film by a homogeneously magnetized ellipsoid of revolution of volume V whose radius R x ϭR y ϭR is much larger than the ''film thickness'' 2R z .…”

Micromagnetics of ultrathin films with perpendicular magnetic anisotropy

Magnetization processes in ultrathin transition-metal films with perpendicular magnetic anisotropy are investigated. By model calculations it is shown that nucleation in ideal films is incoherent and therefore bulklike, whereas the truly ultrathin limit of coherent nucleation is restricted to film patches of small cross-section areas. In ideal monolayers, the nonzero film thickness leads to bulklike nucleation if the lateral dimensions of the film exceed about 1 m. This means that monolayer patches having submicrometer diameters cannot be regarded as ultrathin in a micromagnetic sense. On the other hand, the critical single-domain diameter of ultrathin films is larger by one order of magnitude than expected from bulk-type thin-film calculations.

Der Spin des Elektrons spielt eine grundlegende Rolle z. B. in den elektroschwachen Prozessen der Hochenergiephysik oder auch im Magnetismus. Die Spektroskopie der Festkörper mit polarisierten Elektronen ermöglicht es u. a., auch bei Metallen die von der Dispersion der Elektronenzustände abhängige Austauschaufspaltung zu bestimmen und den Magnetismus der durch die Oberfläche induzierten neuen Zustände zu messen. Kaskadenelektronen werden emittiert, wenn man die Oberfläche mit einem primären Elektronenstrahl von einigen keV mit hoher Intensität und Polarisationsgrad bestrahlt. Sie erweisen sich als ideales Hilfsmittel zur Magnetometrie der Oberflächen und der zweidimensionalen magnetischen Systeme.
