  7. 5. Exploring the Magnetism of Ultra Thin 3d Transition Metal Films

    Författare :Cecilia Andersson; Olof Karis; Dimitri Arvanitis; Chi-Chang Kao; Uppsala universitet; []
    Nyckelord :Physics; thin film; xmcd; xrms; exafs; anisotropy; magnetism; Fe; Ni; Co; Ag; Cu; Fysik;

    Sammanfattning : In this thesis the magnetic and structural properties of ultra-thin 3d transition metals films have been investigated, in particular Fe, Ni and Co films. X-ray Magnetic Circular Dichroism (XMCD) has provided element specific spin (ms ) and orbital (ml ) moments per atom by utilizing the magneto optic sum-rules. LÄS MER
