“…Meanwhile, a broad peak is observed in the dielectric loss curves that move towards the low frequency as the magnetic field is increased, as shown in Figure 3b. These features further confirmed the ME coupling in the as-prepared bilayers [34]. To further investigate the micro-magnetoelectric properties, PFM was used to study the distribution of ferroelectric domains in films under different magnetic fields.…”

Magnetoelectric (ME) magnetic field sensors utilize ME effects in ferroelectric ferromagnetic layered heterostructures to convert magnetic signals into electrical signals. However, the substrate clamping effect greatly limits the design and fabrication of ME composites with high ME coefficients. To reduce the clamping effect and improve the ME response, a flexible ME sensor based on PbZr0.2Ti0.8O3 (PZT)/CoFe2O4 (CFO) ME bilayered heterostructure was deposited on mica substrates via van der Waals oxide heteroepitaxy. A saturated magnetization of 114.5 emu/cm3 was observed in the bilayers. The flexible sensor exhibited a strong ME coefficient of 6.12 V/cm·Oe. The local ME coupling has been confirmed by the evolution of the ferroelectric domain under applied magnetic fields. The flexible ME sensor possessed a stable response with high sensitivity to both AC and DC weak magnetic fields. A high linearity of 0.9988 and sensitivity of 72.65 mV/Oe of the ME sensor were obtained under flat states. The ME output and limit-of-detection under different bending states showed an inferior trend as the bending radius increased. A flexible proximity sensor has been demonstrated, indicating a promising avenue for wearable device applications and significantly broadening the potential application of the flexible ME magnetic field sensors.

Bi-phase multiferroic composites of NiFe2O4/Ba0.94Ca0.06Ti0.975Zr0.025O3 (BCTZ/NFO) were successfully fabricated by high-energy ball milling combined with heat treatment. X-ray diffraction patterns and Raman spectra confirmed the successful coexistence of BCTZ and NFO phases in the final composites, which had an average particle size of 50 nm. However, the number of large particles increased with the increased NFO concentration in the composites. Optical properties of the composites were also modified by the NFO content, where the absorption band tended to the visible region and band-gap energies (E g) decreased with the increase of NFO. Ferromagnetic and ferroelectric properties of the BCTZ/NFO composites were also tuned by NFO additive content. Both saturation magnetisation (M s) and remnant magnetisation (M r) increased with the increase of NFO content, where the maximum values of M s = 22.52 emu g−1 and M r = 1.48 emu g−1 for composites with 40% NFO concentration, while coercivity (H c) was maintained at about 60 Oe. Maximum polarisation (P max), remnant polarisation (P r), and coercive field (E c) values all increased with NFO concentration, with 10% NFO providing the highest P max (= 0.249 μC cm−2) and P r (= 0.116 μC cm−2) values, and 30% NFO providing the highest E c (= 1.720 kV cm−1) value with a maximum applied voltage of 1 kV. Therefore, the multiferroic properties of BCTZ/NFO composites could be enhanced with an appropriate concentration of NFO, which led to a wide range of practical applications in the advanced electronic device field.
