Samples of La(1+x/2)Na(1-x/2)Ti1-xFexO3 were prepared by solid state reaction method. Measurement of XRD and Fe-57 Mossbauer spectra show that, at a lower content of Fe ions, the structures of samples are cubic perovskite, and Fe-57 Mossbauer spectra exhibit a superposition of one doublet and one single paramagnetic line. Their relative intensities change with x. At x>0.7, the structure transforms to orthorhombic and the internal magnetic field is not equal to zero. Fe ions in samples are high spin Fe3+.
