Description

The magnetic properties of ZnO co-doped with 5 at. % Co and 5 at. % Mn(Zn0.90Co0.05Mn0.05O) synthesized by a solid-state reaction were investigated by means of 57Co emission Mössbauer spectroscopy. The majority of the probe ions (80 %) residing in defect-free substitutional Zn sites take the oxidation state of 57Fe 2+, and the others presumably form local defects taking the state of 57Fe 3+ at room temperature. Both components show doublets, and RT ferromagnetism was thus absent in the sample. For the measurement at 10 K, spectral broadening was observed, implying a possible presence of a weak magnetic component.
