abstract = {The magnetic structure and magnetic excitations in
nanocrystalline Tb have been investigated by neutron
diffraction and neutron spectroscopy. This is a report on
the long-range magnetic order and the magnetic excitations
in a nanocrystalline elemental rare earth. Refinement of the
neutron-diffraction data reveals an "average" magnetic
structure of each crystallite which contains a significant
out-of-plane component to the magnetic moment as well as a
suppression of the high-temperature antiferromagnetic phase
observed for coarse-grained Tb. The
inelastic-neutron-scattering measurements reveal the
presence of a magnetic excitation of approximately 10 meV at
2.5 K. The excitation energy decreases with increasing
temperature. The origins of this excitation are discussed
with particular reference to the magnetic modes at the zone
center observed for single-crystal Tb. (C) 2006 American
