We present superparamagnetic clusters of highly disordered Zn-Co-O created by high fluence Co ion implantation into ZnO (0001) single crystals at low temperatures. This secondary phase cannot be detected by x-ray diffraction but by high-resolution transmission electron microscopy. In contrast to many other secondary phases it shows anomalous Hall effect and thus is a candidate for magneto-electronics applications.

Keywords: ZnO; diluted magnetic semiconductors; ion implantation
