Abstract:
As the demand for advanced data storage technology rises, we are exploring materials that
provide precise control. Among the potential applications for two-dimensional materials,
there is a notable interest in exploring multiferroic materials that respond to both electric and
magnetic fields. In this research, we used two-dimensional (2D) layered titanium carbide
(Ti3C2Tx) from the MXene class, La-doped Bismuth Ferrite (BLFO) and La- and Se-co-doped
BFO (BLFSO) to make hybrid composites. Pure Ti3C2Tx is not ferroelectric and exhibits a
very low magnetic response at room temperature, but it shows ferroelectric behavior after
generating new phases of titanium dioxide (TiO2) on its surface upon heat treatment. The
hybrid composites show good ferroelectric and magnetic response which are further
enhanced after annealing. Our results showed that the heated BLFSO-embedded Ti3C2Tx
hybrid composite showed maximum remanent polarization with lower leakage current and
higher dielectric response. The ferroelectric hysteresis loops are consistent at different
frequencies. The prepared samples also exhibited tunable polarization response at an applied
static magnetic field, unveiling their magnetoelectric properties.
