Abstract

Single crystals of iron‐implanted TiO~2~ rutile have been investigated by the electron paramagnetic resonance (EPR) technique at room temperature. The spectra have been interpreted to correspond to the transitions among the spin multiplet (S = 5/2, L = 0) of the paramagnetic Fe^3+^ ions. Analysis of the EPR spectra shows that iron in TiO~2~ rutile host substitutes for Ti^4+^ ions. Two equivalent Fe^3+^ centers have been observed in the EPR spectra in correspondence with two equivalent octahedral positions of the Ti ions in the rutile structure. Parameters of the crystal field of orthorhombic symmetry on the Fe^3+^ centers have been obtained as a result of computer modelling. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
