| Abstract: | In the orthorhombic phase of KnbO3 an EPR spectrum of Fe3+ substitutional for Nb5+ has been observed with the main axis parallel to the pseudocubic one of the orthorhombic phase. The cubic parameter a is very close to the one in BaTiO3. A second spectrum probably due to local charge compensation is also reported. |
