Structural, chemical and electronic properties of the Co2MnSi(001)/MgO interface
Roman Fetzer, Jan-Peter Wüstenberg, Tomoyuki Taira +4
The performance of advanced magnetic tunnel junctions build of ferromagnetic (FM) electrodes and MgO as insulating barrier depends decisively on the properties of the FM/insulator…
Surface spin polarization of the non-stoichiometric Heusler compound Co2Mn(alpha)Si
Jan-Peter Wüstenberg, Mirko Cinchetti, Martin Aeschlimann +6
Using a combined approach of spin-resolved photoemission spectroscopy, band structure and photoemission calculations we investigate the influence of bulk defects and surface states…
Direct determination of the surface termination in full Heusler alloys by means of low energy electron diffraction
Jan-Peter Wüstenberg, Takayuki Ishikawa, Masafumi Yamamoto +4
The performance of Heusler based magnetoresistive multilayer devices depends crucially on the spin polarization and thus on the structural details of the involved surfaces. Using l…
Towards a full Heusler alloy showing room temperature half-metallicity at the surface
M. Cinchetti, J. -P. Wüstenberg, M. Sánchez Albaneda +4
In this article we investigate the surface spin polarization in a 100 nm Co2Cr0.6Fe0.4Al (CCFA) film grown ex situ epitaxially on MgO(100) with a 10 nm Fe buffer layer by means of…
Spin- and time-resolved photoemission studies of thin Co2FeSi Heusler alloy films
J. -P. Wüstenberg, M. Cinchetti, M. Sánchez Albaneda +2
We have studied the possibly half metallic Co2FeSi full Heusler alloy by means of spin- and time-resolved photoemission spectroscopy. For excitation, the second and fourth harmonic…
Spin-flip processes and ultrafast magnetization dynamics in Co - unifying the microscopic and macroscopic view of femtosecond magnetism
M. Cinchetti, M. Sánchez Albaneda, D. Hoffmann +7
The femtosecond magnetization dynamics of a thin cobalt film excited with ultrashort laser pulses has been studied using two complementary pump-probe techniques, namely spin-, ener…
