The morphology of the La0.5Sr0.5Ti1xFexO3 nanopowders was
revealed by SEM (Fig. 2(a)–(c)) and TEM (Fig. 3(a)–(c)). It is obvious
that all of the samples consist of nanoparticles of cubic, plate-like
and irregular shapes with the particle sizes in the range of 312–
609, 166–239, and 187–326 nm, respectively. Similar morphology
of these samples can be also observed by TEM as shown in
