Description	The preparation of complex oxides by the conventional solid-state (ceramic) route requires a number of stages, including homogenization of the powder precursors, compaction of the reactants, and finally prolonged heat treatment at considerably elevated temperatures under controlled oxygen fugacity. One goal of modern materials research and development has been to identify simpler processing schemes that do not rely upon high-temperature treatments for inducing solid-state reactions. At present, mechanochemical methods become widely used for the preparation of nanocrystalline materials due to their relative simplicity and availability. In this work, selected examples of the preparation of nanoscale complex oxides via single-step mechanochemical routes are presented. Nuclear spectroscopic methods are employed to follow the mechanically induced formation of nanooxides and to characterize the nonequilibrium structural state of the resulting nanophases at the atomic level.
