| Abstract: | V tejto publikácii sme študovali polokovú Heuslerovú zliatinu Co2MnSi2 a jej rozhranie s Ag(100) pomocou HAXPES a DFT výpočtou. Porovnaním týchto dvoch metód sme identifikovali elektrónový stav ktorý sa nachádza na rozhraní tźchto dvoch materiálov a má vysokú spinovú polarizáciu ktorá može nájsť uplatnenie v spintronike. |
| Abstract in different language: | We investigated interfaces of halfmetallic Co 2 MnSi(1 0 0) Heusler thin films with Ag(1 0 0), Cr(1 0 0), Cu and Al layers relevant for spin valves by high energy x-ray photoemission spectroscopy (HAXPES). Experiments on Co 2 MnSi samples with an Ag(1 0 0) interface showed a characteristic spectral shoulder feature close to the Fermi edge, which is strongly diminished or suppressed at Co 2 MnSi (1 0 0) interfaces with the other metallic layers. This feature is found to be directly related to the Co 2 MnSi(1 0 0) layer, as reflected by control experiments with reference non-magnetic films, i.e. without the Heusler layer. By comparison with HAXPES calculations, the shoulder feature is identified as originating from an interface state related to a highly spin polarized surface resonance of Co 2 MnSi (1 0 0). |
