38. Note that the theoretical calculated density of MnO single crystal is 5.366 g/cm 3, and the actual density of the nanoparticle pellet is 2.54 g/cm 3. Pellet density is therefore ~ 47% of the single crystal density, a difference that we correct for in our analysis.

51. The smaller value of the low temperature local effective charge in the lower branch indicates a reduced ionic interaction in the [111] direction.
52. The error bars are similar for both materials (Ref. 49), but the y -scale in Figs., , and is significantly smaller than that for single crystal [Figs., , and], which makes the nanoparticle data appear more scattered.

55. - 13 s, infrared spectroscopy is able to resolve the splitting in the single crystal sample, but it captures only an average response for the nanoparticles. This is why the TO phonon does not appear to split for nanoscale MnO.

63. The latter is important because the antiferromagnetic portion is the part that engages in spin-phonon coupling. Reduced crystalline anisotropy may also play a role by facilitating spin reorientation in the nanoparticles compared to the bulk.
