The formation of secondary phases inside yttria stabilized zirconia (YSZ) crystals implanted with Fe ions was investigated by means of synchrotron radiation x-ray diffraction, conversion electron Mössbauer spectroscopy, and x-ray diffraction reciprocal space mapping. Fe ions have been implanted into single crystals of YSZ(001) at elevated temperatures. As the implanted ion fluence is increased an increase in α-Fe cluster formation was observed, along with the appearance of γ-Fe and secondary phases of Fe oxide(s). The clusters are proposed to consist of a metallic core and an oxide shell. Ferromagnetic hyperfine splitting was detected by Mössbauer spectroscopy and was mainly attributed to the presence of Fe3+ and α-Fe. [ABSTRACT FROM AUTHOR] |
