AbstractWe demonstrate the detection of Magnetic X-ray Circular Dichroism (MXCD) from commercial, thin-film spin valves. Measured x-ray absorption spectra on these devices indicate magnetic polarization of the ferromagnetic constituents, Fe, Co, and Ni.

Circular Dichroïsm

The effect of capping with Cu, Au and Pt of an array of Co nanoparticles is revised. The magnetic surface anisotropy KS was found to be the dominant contribution to the effective anisotropy Keff of the particles. Recent X-ray Magnetic Circular Dichroism (XMCD) measurements show that there is hybridization between the 3d Co electrons and the d and 4p electrons of the capping metal. By comparison to the mechanisms which give rise to the surface anisotropy in thin films, it is argued that this hybridization governs the modification of KS, and hence, of Keff.
