The electron spin resonance spectra of Gd3+ in ceramic PbTiO3 and, as a comparison, in powdered Bi3Mg2(NO3)12·24H2O are reported. The interpretation, in terms of crystal field parameters, of the spectrum of the double nitrate is in good agreement with previous single crystal results. It was not possible to interpret the room temperature spectrum of PbTiO3. However, the spectrum of this compound measured above its Curie-temperature (763 K) can be interpreted. This shows that the local crystal field symmetry of a small part of the Gd3+-ions at this temperature is orthorhombic or lower, not-withstanding the cubic lattice symmetry of PbTiO3 under these conditions.
