摘要：

The observation of two new electron paramagnetic resonance (EPR) spectra in p-type silicon doped with aluminium and iron is reported. Both spectra, labelled Si-NL40 and Si-NL41, have monoclinic-I symmetry and can be described as a paramagnetic system with a spin S = 1/2 and g-values greatly deviating from that of a free electron, as well as by a spin S = 5/2 and g-values close to g = 2. The analysis of the spectra with spin S = 5/2 allowed to determine the relative values of the zero-field splitting parameters D and E. A good agreement with the theoretical calculation for the relationship between the components of the g-tensor and the value E/D is obtained. From the resolved hyperfine structure due to Al-27, which is observed for some EPR orientations, and the analysis of g-values both centres are suggested to be FeFeAl complexes.
