“…Multiferroics materials that simultaneously exhibit two or more primary ferroic ordering like ferroelectric (FE), ferromagnetic (FM), and ferroelastic, are of immense technological importance 1 . The underlying physics in these classes of materials and their utilization for the development of multifunctional devices have drawn tremendous research interest among the scientific community 2 . The term “Magnetoelectric” is associated with the coupling between ferroelectric and magnetic order parameters.…”

“…Owing to the mutual exclusiveness and chemical incompatibility for the occurrence of ferroelectricity and magnetism, single-phase multiferroics with strong magneto-electric coupling are very rare in nature. Generally, multiferroic materials are available in the form of single-phase and composite structures 2 . Single-phase magneto-electric multiferroic systems possess at least two primary ferroic orders in a single system whereas composites refer to multiphase materials with multiferroic properties arising out of the interactions of respective phases 4 .…”

“…Most of the available single-phase room temperature (RT) multiferroic materials show very weak ME coupling due to the independent ordering of ferroelectricity (FE) and magnetism. On the other hand, they show good ME coupling at cryogenic temperatures (magnetic/FE transitions are below RT) 2 , 5 . Strong ME coupling between “M” and “P” around and above RT is the essential requirement for the realization of multifunctional devices 4 , 6 .…”

Multiferroic composites are promising candidates for magnetic field sensors, next-generation low power memory and spintronic devices, as they exhibit much higher magnetoelectric (ME) coupling and coupled ordering parameters compared to the single-phase multiferroics. Hence, the 3-0 type particulate multiferroic composites having general formula (1 − Φ)[PbFe0.5Nb0.5O3]-Φ[Co0.6Zn0.4Fe1.7Mn0.3O4] (Φ = 0.0, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 1.0, (1 − Φ) PFN-ΦCZFMO) were prepared using a hybrid synthesis technique. Preliminary structural and microstructural analysis were carried out using XRD and FESEM techniques, which suggest the formation of 3-0 type particulate composite without the presence of any impurity phases. The multiferroic behaviour of the composites is studied with polarization versus electric field (P-E) and magnetization versus magnetic field (M-H) characteristics at room temperature. The nature of ME coupling was investigated elaborately by employing the Landau free energy equation along with the magneto-capacitance measurement. This investigation suggests the existence of biquadratic nature of ME coupling (P2M2). The magneto-electric coupling measurement also suggests that strain mediated domain coupling between the ferroelectric and magnetic ordering is responsible for the magneto-electric behaviour. The obtained value of direct ME coefficient 26.78 mV/cm-Oe for Φ = 0.3, found to be higher than the well-known single-phase materials and polycrystalline composites.

“…6 However, the experimental reports are controversial. Both equivalence 6,7 and inequality [8][9][10] of the direct and converse magnetoelectric effects have been reported. The discrepancy is related to a variation in measurement parameters (excitation frequency, magnetic, and electric fields) as well as to different boundary conditions.…”

We report on a systematic study of the magnetoelectric effect in cobalt ferrite (CoFe2O4)—barium titanate (BaTiO3) ceramic composites with (0‐3) connectivity. Both the converse magnetoelectric coefficient, αC, and the direct voltage magnetoelectric coefficient, αE, were measured in dependence on composition and electric and magnetic bias fields. The strongest ME effect was observed in the composition (1−x) CoFe2O4–xBaTiO3 with x = 0.5 yielding values αC = 25 psm−1 and αE = 3.2 mV/(cm·Oe). We show that the proper conversion between these two coefficients demands knowledge about the dielectric permittivity of the sample. For low BaTiO3 content the dielectric coefficient of the composite yields a better correspondence, whereas for high BaTiO3 content the sample's average dielectric coefficient yields a better match. The influence of mutual orientation of polarization and magnetization on the ME effect is addressed. We found that for measurements performed parallel to the polarization direction (longitudinal effect), the ME coefficient is approximately twice as large and of opposite sign in comparison to the measurements perpendicular to the polarization direction (transverse effect). This difference has been rationalized in terms of the different contributions of the material coefficient tensor components to the ME effect, the demagnetizing factor, and losses. The obtained results provide a better understanding of peculiarities of the ME effect in bulk ceramic composites.

“…Materials that primarily exhibit more than one ferroic orders (ferroelectric, ferromagnetic, etc) are referred to as multiferroics (MF), offering massive technological benefits [1][2][3] . In MF materials, either an external electric field can control the magnetic domains and/or an external magnetic field can regulate the electric domains owing to the magnetoelectric (ME) coupling 4 .…”

Multiferroic and ferroelectric phases revealed in 2D Ti3C2Tx MXene film for high performance resistive data storage devices

Multiferroic materials, showing simultaneous ferroelectric and ferromagnetic orders, are considered to be promising candidates for future data storage technology however, the multiferroic phenomenon in two-dimensional (2D) materials is rarely observed. We report a simple approach to observe frequency-dependent ferroelectricity and multiferroicity in 2D Ti3C2Tx MXene film at room-temperature. To study the frequency and poling effect on ferroelectricity, we performed electric polarization vs. electric field (P-E) measurement at different frequencies, measured under zero and non-zero static magnetic fields. The results not only indicate a clear frequency dependence of electric domains owing to varying time relaxation during reversal dynamic but also showed magnetic field control of electric polarization thus, confirmed the presence of strong magneto-electric (ME) coupling at room-temperature. The existence of ME coupling was attributed to the coupling between disordered electric dipoles with local spin moments as well reduced dielectric loss after heat-treatment. Moreover, the ferroelectric Ti3C2Tx MXene film was employed as an active layer within the resistive data storage device that showed a stable switching behavior along with improved on/off ratio in comparison to non-ferroelectric Ti3C2Tx active layer. The unique multiferroic behavior along with ferroelectric-tuned data storage devices reported here, will help understand the intrinsic nature of 2D materials and will advance the 2D ferroelectric data storage industry.
