  We report a surfactant assisted synthesis of Mn doped ZnO polycrystalline
samples showing robust room temperature ferromagnetism as characterized by
X-ray diffraction analysis, Transmission Electron Microscopy, Electron
Paramagnetic Resonance and DC magnetization mearurements. This surfactant
assisted synthesis method, developed by us, is found to be highly reproducible.
Further, it can also be extended to the synthesis of other transition metal
doped ZnO.
