Sy. Tong et al., ANGLE-RESOLVED X-RAY CIRCULAR AND MAGNETIC CIRCULAR DICHROISMS - DEFINITIONS AND APPLICATIONS, Physical review. B, Condensed matter, 54(21), 1996, pp. 15356-15362
We introduce definitions of angle-resolved x-ray circular dichroism (A
RXCD) and magnetic x-ray circular dichroism (ARMXCD). As defined, the
much larger effect pf circular dichroism (ARXCD) is separated from the
smaller magnetic (ARMXCD) effect. In all materials, ARXCD is zero alo
ng minor planes while nonzero elsewhere ARMXCD is nonzero only in magn
etic materials. The measurement and analysis of ARMXCD allow element s
pecific surface magnetism and surface structure as well as their inter
-relationship to be studied as functions of the outgoing of electrons
direction.
