Fe-doped and (Fe, Cu)-codoped TiO2 powders were prepared by mechanical alloying. The structure, chemical composition and magnetic properties of samples were investigated with X-ray diffraction (XRD), inductively coupled plasma atomic emission spectrometry, 57Fe Mössbauer spectroscopy, X-ray photoelectron spectroscopy (XPS) and vibrating sample magnetometer (VSM). XRD patterns show that all milled...
