Query: Monitoring transitions between antiferromagnetic states of individual
  molecules   Spin-electronic devices are poised to become part of mainstream
microelectronic technology. Downsizing them, however, faces the intrinsic
difficulty that as ferromagnets become smaller, it becomes more difficult to
stabilize their magnetic moment. Antiferromagnets are much more stable, and
thus research on antiferromagnetic spintronics has developed into a
fast-growing field. Here, we provide proof of concept data that allows us to
expand the area of antiferromagnetic spintronics to the hitherto elusive level
of individual molecules. In contrast to all previous work on molecular
spintronics, our detection scheme of the molecule's spin state does not rely on
a magnetic moment. Instead, we use the step-like transitions between several
distinct current levels caused by transitions between different
antiferromagnetic states of an individual molecule grafted onto a carbon
nanotube. We find that in the absence of an orbital momentum the
antiferromagnetic spin states of the molecules show coherent superposition.
