AB  - The search for multiferroic materials combining electric and magnetic properties in a single phase has attracted
a lot of attention in the perspective of future magnetoelectronic devices. A handful of single phase multiferroics
have been discovered so far, and most of them are not suitable for practical applications at present, either
because the room temperature polarization/magnetization is too small or their mutual coupling is too weak.
One of the most important single-phase multiferroic material with Aurivillius structure is Bi5Ti3FeO15 (BFT)
which generally yields a magnetoelectric coupling above room temperature. The main lack of this material is
high electrical conductivity and hence the lower ferro-electromagnetic properties. 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 of the structure.
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). Slightly improve of ferroelectric properties
was noticed with 0.3 mol% of Co while replacement of Bi3+ with Y3+ causes a reduction in orbital hybridization
between Bi 6sand O 2s/2porbitals leading to a decrease in electric polarization as a vector sum of all dipole
moments. Magnetic measurements confirm the antiferromagnetic nature of pure and Y doped ceramics while
Co-doped samples exhibit a typical ferromagnetic loop reveals the existence of FM interactions in these samples.
The largest Mr value appears in samples doped with 3 mol% of Co (Mr of 0.084 emu/g and Hc of 287 Oe). Raman
spectroscopy confirmed that Y prefer to replace Bi ions in the pseudo-perovkite layers while Co ions enter into
the lattice and occupy the Fe site inside of oxygen octahedral.

AB  - Bismuth ferrite (BiFeO3) and bismuth titanate ferrite (Bi5Ti3FeO15) are studied a
lot in recent years because of their specific structure and potential to act as single phase
multiferrioics. Thanks to the optical band gap energy of 2.3-2.8 eV for BiFeO3 and 1.8-
2.3 eV for Bi5Ti3FeO15, these materials are also interesting for photocatalytic and solar
energy applications, and studies of using Bi5Ti3FeO15 for this purpose are very rare. Solgel
methods were used to produce BiFeO3 and BiFeO3-modified diatomaceous earth,
while Bi5Ti3FeO15 was obtained sol-gel and solid-state methods. These powders were
characterized, and their visible light photocatalytic activity for decomposition of
methylene blue was tested in acidic, close-to-neutral and alkaline conditions. Fenton-like
catalysis was also tested. Influence of synthesis method, microstructure, and catalyst
composition on dye degradation will help in proposing the mechanism of adsorption and
photocatalytic processes.

AB  - One 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.
