Circular Dichroïsm

ABSTRACTRecent results on the dependence of the magnetic circular dichroism on the angle and temperature for thick (100 ML) films of Gd(0001) are presented. Strong dichroic effects were observed in 4d core-level photoemission for the magnetized films, which showed excellent agreement with an atomic many-particle description recently published [1]. The angular dependence of the magnetic dichroism has been discussed taking into account photoelectron diffraction effects. In addition, an indication of a higher surface Curie temperature has been observed in the temperature- dependent measurements.

Circular Dichroïsm

The angular dependence of the circular dichroism in photoemission from Pt(111) was investigated for excitation with VUV and soft X-ray radiation. VUV excitation was used to probe band structure and the circular dichroism for valence band emission. The measurements are compared to full relativistic single step photoemission calculations. XPS was used to investigate the circular dichroism in emission from the 4f core level. In this case, the dichroism is induced by photoelectron diffraction. First results from single step core level calculations are compared to the experimental observations.

Circular Dichroïsm

The observation of magnetic circular dichroism in the angular distribution of photoelectrons (MCDAD) from alkali and rare-gas films adsorbed on a thin remanently magnetized Co layer is reported. The observation of an antisymmetric MCDAD near normal emission for Co(0001)–Cs 5p semi core level is shown. The reversed magnetization leads to a mirror-image-like distribution. The second system under investigation, physisorbed Co(0001)–Xe 5p, does not give such an but shows significant differences in the MCDAD signal for both directions of magnetization, in particular in the |mj| substates of the p3/2 level. A magnetic coupling between Xe and Co is evident when we take results of spin-resolved photoemission into account.
