Abstract
An unusual sequence of magnetic couplings in the epitaxial-growth system Mn / Fe(110) is revealed using the element-selective magnetic circular X-ray d ichroism (MCXD) method. Clean Mn shows an unprecedented vanishing magnetiza tion up to 0.3 monolayers (ML). At 0.4 ML a parallel Mn-Fe coupling sets in with relatively small net Mn moment (1.0 +/- 0.2 mu(B) for 0.4-2 ML). Succ essive adsorption of oxygen changes the Mn-Fe coupling from parallel to zer o to antiparallel and eventually to zero again.
