An unusual sequence of magnetic couplings in the epitaxial-growth
system Mn/ Fe(110) is revealed using the element-selective
magnetic circular X-ray dichroism (MCXD) method.
Clean Mn shows an unprecedented vanishing magnetization up to
0.3 monolayers (ML). At 0.4 ML a parallel Mn-Fe coupling sets in
with relatively small net Mn moment
(
for 0.4–2 ML).
Successive adsorption of oxygen changes the Mn-Fe coupling
from parallel to zero to antiparallel and
eventually to zero again.
