An element-selective investigation of magnetism on carbon in the
vicinity of atoms in a
multilayer is
reported. We utilize resonant magnetic reflectivity of circularly
polarized synchrotron radiation which allows us to distinguish
unambiguously the local magnetism on carbon from that on
through individual core-level excitations. Clear magnetic signals
of carbon are obtained by exploiting the standing-wave technique.
Hysteresis loops of individually excited
and
atoms demonstrate ferromagnetism of
at room temperature
with a moment of
induced by adjacent
atoms.
