Abstract = {{We used resonant inelastic x-ray scattering (RIXS) at the Ni L-3 edge to
   measure the dispersion of spin waves in NiO thin films along the
   {[}101], {[} 001], and {[}111] directions. Samples with tensile and
   compressive in-plane strain show identical dispersion within the
   experimental uncertainty. The fitting of the data with a linear spin
   wave model applied to a three-dimensional Heisenberg antiferromagnetic
   lattice provides a leading superexchange parameter J' = 18 meV. The
   magnon energy at the Brillouin zone boundary and the value of J' are 5%
   smaller than those determined by inelastic neutron scattering on bulk
   single crystals. This discrepancy is likely induced by the strain or
   other structural differences between bulk and epitaxially grown samples.
   These results demonstrate the capabilities of high-resolution RIXS in
   the study of the magnetic structure of thin films and heterostructures
   for which neutron scattering is not sensitive enough.}},
