題目：Elastic and inelastic interactions of spin polarized electrons in tunneling spectroscopy

Abstract:
The first part of my talk will be devoted to the electronic analysis of
magnetic islands on a nonmagnetic substrate. Energy- and spin-dependent
confined surface states will be analyzed and discussed. In particular, the
spin-polarization of magnetic surface states will be shown.
Secondly the mechanism of magnon excitation by spin-polarized electrons is discussed.
The magnetic excitations by a STM tip will be then presented, both parallel to
the surface (no dispersion) and perpendicular (with dispersion).
Finally some remarks on the role of the exchange-correlation hole in tunneling microscopy
shall be made.
