Abstract:

Mn+-implanted alpha-SiO2-samples were studied with the help of soft X-ray emission and absorption spectroscopy (Si L-2.3 3d3s -> 2p(3/2,1/2) and Mn L-2.3 3d4s -> 2P(3/2,1/2) emission transitions) using synchrotron excitation. The samples were obtained using a pulsed ion source (ion beam current density similar to 2-7 mA/cm(2), E-impl. = 30 keV, ion fluence similar to 2 x 10(17) cm(-2), pulse duration 400 mu s) without thermal annealing. It was established that Mn-ion provides a formal valence state 2+, so arranging in implanted alpha-SiO2 the low-sized MnO antiferromagnetic clusters probably of crystalline type. The data obtained well coincides with the electronic spin resonance results reported earlier. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.
