Two series of oxynitride glasses, RE–Si–Mg–O–N ( M = Mg , Al ; RE = La , Lu), have been studied by X-Ray photoelectron spectroscopy (XPS). The oxygen 1s photoelectron lineshape reveals a striking difference depending on the rare earth, both i

The aim of the present work was to evaluate the ability of reflection electron energy loss spectroscopy (REELS) as a non-destructive method to obtain depth profiles of dielectric constants, in a complementary way to transmission electron energy loss

The giant magnetoresistance (GMR) of multilayers in the current in plane (CIP) geometry can be understood by considering the spin-dependent scattering effects within the magnetic layers and at the non-magnetic/magnetic interfaces. In this paper we ex

In this paper, a detailed study of the magnetic behaviour particularly at the Verwey transition is presented for some stoichiometric magnetite samples, as a function of their shape (film/bulk) and crystalline structure (single/polycrystal). Travellin

A new pair of Kramers–Kronig (KK) dispersion relationships for the transformation of surface energy loss function Im[−1/(e + 1)] has been proposed. The validity of the new surface KK transform is confirmed, using both a Lorentz oscillator model a

In order to confine specific long-life actinides, originating from high-level nuclear wastes, lanthanum aluminosilicate glasses are considered. The aqueous corrosion behavior of these glasses is studied under static conditions ( T=96 ° C, duration b
