    • "Broken exchange bonds" are distinct from the idea of "spin pinning" proposed in the initial study (Ref. 5). Our recent measurements on a sample milled without surfactant show all the same anomalous effects, differing quantitatively by less than a factor of 2. In conjunction with the results of our calculation, this leads us to believe that chemical species other than surfactants can bind to surface ions and break exchang bonds. Surfactant removal by heating as performed in the initial study incurs the possibility of sintering and surface oxidation, which can act to decrease the sruface area and "heal" the broken bonds, thus reducing the surface spin disorder.
