摘要: Prompted by the generally poor understanding of nature magnetic phenomena in 3d-metal doped ZnO, we have undertaken on-line F57e Mossbauer spectroscopy on ZnO single crystals an external field 0.6 T, following implantation radioactive M57n ions at room temperature. The spectra dilute Fe impurities are dominated sextets whose angular dependence rules out ordered state (which had been previously proposed) but well accounted for basis Fe3+ paramagnetic centers substitutional Zn sites with unusually long relaxation times (>20 ns).
