Description

This book describes energy loss magnetic chiral dichroism (EMCD), a phenomenon in energy loss spectroscopy discovered in 2006. EMCD is the equivalent of XMCD but is based on fast probe electrons in the electron microscope. A spatial resolution of 2 nm has been demonstrated, and the lattice-resolved mapping of atomic spins appears feasible. EMCD is,

About the Editor

Peter Schattschneider studied physics at the Vienna University of Technology, Austria, and finished in 1973 with a diploma thesis on diffusion profiles in thin films. In 1974, he enrolled in the study of college teacher for physics and mathematics at the University of Vienna and obtained a mag. rer. nat. degree in 1977. After his PhD thesis on X-ray diffraction of binary alloys, he left Vienna University of Technology in 1976 and came back in 1980 as assistant at the Institute for Applied and Technical Physics. In the meantime, he worked in an engineering enterprise, dealing with remote sensing (air- and spaceborne sensors). In 1981, he obtained the Theodor-Korner award for work on the EEL spectrometer installed at the old ELMISKOP IA. In 1988, he became assistant professor at the Institute for Applied and Technical Physics of the Vienna University of Technology, where his main research interests were electron microscopy, inelastic electron-matter interactions, and electron energy-loss spectrometry. In 1992 and 1993, he was employed by the CNRS (Centre Nationale de la Recherche Scientifique) in Paris. Since 1995, he has been professeur invite at the ecole Centrale Paris. From January 2000 to June 2006, he was head of the University Service Center for Transmission Electron Microscopy (USTEM).
