Abstract: This paper analysis the temperature dependence of FC and ZFC magnetization for Bi$_5$FeTi$_3$O$_{15}$ multiferroic. It has Aurivillius four-layer phase structure. The analysis evidence on the influence of the grains of this material on its overall magnetic properties. The lack of a dramatic temperature threshold in the FC(ZFC) dependences may result in spin canting induced by the Dzyaloshinskii–Moriya interaction.

Keywords: Aurivillius phases, perovskites, magnetic properties.
