It has been established that the degree of isomorphous substitution in the bismuth sublattice and thermal stability of phases tend to reduce with the increasing h. It has been demonstrated that the magnetic ions inside the perovskite-like block can have antiferromagnetic interaction exchange that influences magnetic properties of the Aurivillius phases. </p></abstract><kwd-group xml:lang="en"><kwd>aurivillius phases</kwd><kwd>nanolayers</kwd><kwd>perovskite-like nanoblocks</kwd><kwd>formation mechanism</kwd><kwd>thermal properties</kwd><kwd>magnetic properties</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was financially supported by the Russian Foundation for Basic Research (Grant No. 16-03-01056).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Keeney L., Downing C., Schmidt M., Pemble M.E., Nicolosi V., Whatmore R.W.
