“…We also expect that the Co layers have their polar component close to the saturated value everywhere except for low magnetic fields. Therefore, and represent MO contributions of Co films and the matrix is in the form (5) According to (4), we calculate the inverse matrix of (5), from which the coefficients for separation are obtained. Using the coefficients the separated hysteresis loops of Co and NiFe layers are calculated from original loops "point by point" as a function of the applied magnetic field.…”

“…The main advantages of the MO techniques are their high near-surface sensitivity, nondestructive character, and possibility to measure all components of the magnetization vector in the frame of the magneto-optic vector magnetometry [2], [3]. The depth sensitivity of MO effects was systematically studied by Traeger [4] and Hubert [5] using modeling of the MO effect from a buried thin magnetic layer in a nonmagnetic surrounding. Separation of polar MO signal from films in different depths was presented by Ferré [6] and Hamrle et al [7], [8] in the case of Co films separated by Au spacer.…”

Material selective sensitivity of a magneto-optical polar Kerr effect to magnetizations of films from different materials in a multilayer system is presented. The method is supported by rigorous modeling of magneto-optic response from the multilayer system and by experimental demonstration on the periodic cobalt-permalloy multilayers [Ni 80 Fe 20 (2 nm)/Au(2 nm)/Co(0.4, 0.8, and 1.2 nm)/Au(2 nm)] 10 .

Selective sensitivity of ellipsometry to magnetic nanostructures

et al. 2011

View full text Add to dashboard Cite

Magneto-optic (MO) ellipsometry of ferromagnetic materials is extremely sensitive to ultra-thin films, multilayers, and nanostructures. It gives a possibility to measure all components of the magnetization vector in the frame of the magneto-optic vector magnetometry and enable us to separate magnetic contributions from different depths and materials in nanostructures, which is reviewed in this article. The method is based on ellipsometric separation using the selective MO Kerr effect. The figure of merit used to quantify the ellipsometric selectivity to magnetic nanostructures is defined on the basis of linear matrix algebra. We show that the method can be also used to separate MO contributions from areas of the same ferromagnetic materials deposited on different buffer layers. The method is demonstrated using both: (i) modeling of the MO ellipsometry response and (ii) MO measurement of ultra-thin Co islands epitaxially grown on self-organized gold islands on Mo/Al 2 O 3 buffer layer prepared using the molecular beam epitaxy at elevated temperatures. The system is studied using longitudinal (in-plane) and polar (perpendicular) MO Kerr effects.
