The mean size of coherent scattering regions of GdFeO3 was determined to be equal to 53, 68 and 73 nm. The observed regularities allowed us to assume the oriented attachment of nanocrystals.</p></abstract><kwd-group xml:lang="en"><kwd>nanoparticles</kwd><kwd>hydrothermal synthesis</kwd><kwd>nucleation</kwd><kwd>phase formation</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The authors would like to thank Prof. V.V.
