Description

A new electron trapped Fe+-type centre produced in SrCl2:Fe single crystals grown in chlorine atmosphere and X-ray irradiated at 80 K has been analysed using Electron Paramagnetic Resonance (EPR). The Fe+(IIa) centre (S=1/2) exhibits monoclinic local symmetry with the two g-tensor principal axes in a {110} plane being slightly tilted away from <001> and <1-10>. The EPR parameters have been determined and discussed in correlation with those of the tetragonal Fe+(II) paramagnetic centre. The Fe+(IIa) centre seems to consist of a fourfold coordinated Fe+ ion slightly perturbed by a neighbouring defect. (copyright 2005 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)
