dc.description.abstractOne of the most important single-phase multiferroic materials with Aurivillius structure is Bi5Ti3FeO15 (BFT) which generally yields a magnetoelectric coupling above room temperature with a magnetoelectric coefficient of 10 mV/cmOe [1]. It has a special interest in this family of compounds because it is a combination of multiferroic BiFeO3 and ferroelectric Bi4Ti3O12 and can be used as new magnetoelectric material for different devices. Years of intensive research have shown that the main lack of this material is high electrical conductivity and hence the low ferro-electromagnetic properties. This is a common problem in single-phase multiferroics, in general. Although they are expected to produce an applications breakthrough, they show poor properties at room temperature. Since BFT has the capability to host ions of different size, multiferroic properties could be improved by using dopants or ionic substitutions on different A and B-sites within the perovskitelike layers [2]. Insertion of magnetic ion such as Co3+ at B-sites could increase the remnant magnetization in BFT ceramics while Y3+ could enhance the dielectric and ferroelectric properties. To this respect, Co2+ and Y3+ doped BFT were prepared by the solid state reaction method according to formulas: Bi1-xYxTi3FeO15 (x = 0.1, 0.2, 0.3) and BiTi3Fe1-yCoyO15 (y = 0.1, 0.3, 0.5). XRD data confirm the formation of singlephase Aurivillius compounds. SEM micrographs show an evident decrease in grain size of Co modified ceramics in comparison with pure BFT while there is no particular change of the grain size with Y doping. The ferroelectric and magnetic properties of all ceramic composites were also studied. Raman spectroscopy in dependence of temperature was used to give an insight to the possible ferroelectric character of BFT and also the way that dopants could influence the structural mechanism affecting the material’s properties at the main magnetic and ferroelectric transitions.sr
