We have successfully performed an $$^{17}$$O NMR for the first time on Americium dioxide (AmO$$_2$$). We observed a drastic broadening of the NMR spectrum, after a sudden drop of NMR signal intensity below $$T_0$$. These data provide the first microscopic evidence for a phase transition as a bulk property in this system. In the ordered state, we found a spectrum with a triangular line shape, which resembles neither that of UO$$_2$$ nor NpO$$_2$$. It is also suggested that there is considerable damage to the sample induced by self-radiation effects from the alpha decay of $$^{243}$$Am.
