A novel processing scheme has been developed that allows for the single step processing of nanostructured complex oxides. This approach involves the high energy ball-milling (HEBM) of binary oxide precursors to form pure phase complex oxides at low-temperatures. Using this technique we have prepared Lao.67Cao.33MnO3. 8 and studied the evolution of short range and long-range order, using EXAFS and XRD respectively, as a function of milling time during the solid state transformation. Transport properties of the milled perovskites are also discussed.
