Erratum to ‘‘Hyperfine characterization of SrTi(x)Hf(1x)O3’’ [Physica B 389(1) 2007 111–115] Alberto Lopez Garcia, Roberto E. Alonso Department of Physics, Universidad Nacional de La Plata, Calles 115 Y 49, C.C.67, 1900 La Plata, Buenos Aires, Argentina Received 1 November 2007; received in revised form 20 November 2007; accepted 27 November 2007

The X-ray diffraction data of SrTixHf1xO3 for x ¼ 0.25, 0.50 and 0.75 were fitted again because the authors realise that a confusion in the nomenclature of these data have been occurred. A new fitting procedure was done, being the composition a free parameter and allowing a new determination of the respective lattice constants and atomic positions. The fitted compositions are close to the nominal values. See Table 1. In Fig. 1 of Ref. [1] the correct insets from top are: x ¼ 0.75, x ¼ 0.50 and x ¼ 0.25, respectively. These corrections do not affect neither the analysis nor the conclusions in the paper.
