Abstract
The 3d core levels photoemission spectra of Rh(100) show linear magnetic di chroism in angular distribution (LMDAD) upon reversing the magnetic field i n chiral experiments only when a small residual magnetic field is left appl ied to the sample. The intensity of the LMDAD effect does not depend on the magnitnde of the applied residual field, but it saturates for very weak fi eld intensities. (C) 2000 Elsevier Science B.V. All rights reserved.
