MAGNETIC DICHROISM FOR PHOTOEMISSION

In recent years, the Magnetic Dichroism for Photoemission(MDPE), integrating the merits of photoelectron spectroscopy and magneto optic technology, is becoming an important method for the investigation of magnetism in such low dimensional systems as surface, interface and thin films. In this paper, the principal and experimental aspects of MDPE are summarized, and the characteristics and theoretical treatment of several MDPE effects are discussed with emphasis. Also its applications are introduced in the studies of the magnetism in low dimensional systems of transition metals and rare earth metals.
