    • The geochronologic (U-Pb isotopic system of zircons) and isotopic-geochemical (Sm-Nd isotopic system of the bulk rock) studies were performed along the profile extending from the eastern Sarmatia (in the west) to the Middle Volga megablock of Volgo-Uralia (in the east), i.e., across the entire junction zone for dating the integration of Sarmatia and Volgo-Uralia, representing two segments of the East European Craton. It is established that the examined rocks are characterized by the Paleoproterozoic Nd isotopic model age, which varies from 2.1 and 2.4 Ga, except for some samples indicating a similar age of the crust through the entire Sarmatia-Volgo-Uralia junction zone. The highly metamorphosed complexes of the granulite and amphibolite facies constituting the southwestern margin of Volgo-Uralia are Paleoproterozoic, not Archean, in age, contrary to previous views. Two Early Paleoproterozoic lithotectonic complexes are defined in Volgo-Uralia: South Volga metasedimentary and Tersa metasedimentary-volcanogenic. The obtained data confirm the asynchronous integration of individual segments into the East European Craton: the integration of Sarmatia and Volgo-Uralia approximately 2100-2000 Ma ago was followed by the conjunction of this newly-formed continent with Fennoscandia ca. 1800 Ma ago.

  • On The Interface Magnetism Of Thin Oxidized Co Films : Orbital And Spin Moments
  • 2009
  • Ingår i: Journal of Physics. - : IOP Publishing. - 0953-8984 .- 1361-648X. ; 21:12, s. 124211-
  • Tidskriftsartikel (refereegranskat)abstract
    • An x-ray magnetic circular dichroism study of a polycrystalline Co/CoO   bilayer is presented. Using both the chemical specificity and surface   sensitivity in the core level techniques, we find that uncompensated   Co2+ spin moments participate in the remanent ferromagnetic response of   the bilayer that has oxygen nearest neighbors. These are likely located   at the Co/CoO interface. As intermixing of magnetic species is not   present in Co/CoO, it is concluded that the observed interface moments   are due to interface roughness. Given their direction, these moments   appear to not directly correlate to the exchange bias in these bilayers.
