“…Figure a shows the H dependence of P for the sample at 315 K. It is interesting that P has the finite spontaneous value at zero magnetic field, which suggests that In‐BSZFO exhibits a transverse conical state. A similar feature has also been found in the previous studies . With increasing H , P is considerably suppressed, indicating a strong ME coupling.…”

The enhanced magnetoelectric properties of Ba0.5Sr1.5Zn2(In0.08Fe0.92)12O22 are demonstrated. This hexaferrite exhibits great magnetoelectric tunability and high electrical resistivity. Mutual modulation of ferroelectricity and magnetism is simultaneously achieved near room temperature. Moreover, the reversal of M direction by an electrical field is obtained at low magnetic field. This study illuminates a potential application in magnetoelectric devices.

“…However, the weak magnetoelectric coupling and low Curie temperature may limit their application prospective. M-type hexagonal ferrite, on the other hand, has been reported to be multiferroic and show a larger room temperature magnetoelectric coupling effect than other compounds [24][25][26][27][28]. M-type hexagonal ferrite is a traditional ferrimagnetism material and has been widely used in the development of magneto-dielectric devices and fabrication techniques at very low costs [29,30].…”

The potential application of multiferroic materials in new electronic devices attracts more and more attention from people either in an academic field or industry. This paper reports that M-type lanthanum-doped barium ferrite (La0.75Ba0.25Fe12O19) demonstrates full antiferroelectric (AFE) and excellent magnetoelectric coupling effects at room temperature, while its AFE phase displays a zero macroscopic net polarization. The dramatic change in the dielectric constant near the Curie temperature far below room temperature represents the transition from ferroelectrics (FE) to antiferroelectrics. The fully separated double electric polarization hysteresis (P–E) loops confirmed its AFE performance. Its EF and EA are located at 1100 kV/cm and 850 kV/cm, respectively. The large M–H loop showed a strong magnetic property simultaneously. The UV-Vis-NIR optical spectrum revealed that La0.75Ba0.25Fe12O19 is also a semiconductor, whose direct bandgap energy (Eg) was determined to be 1.753 eV. Meanwhile, La0.75Ba0.25Fe12O19 showed strong ME coupling and a GMR effect. A 1.1 T magnetic field reduced its resistance by 110% at 30 kHz. The multiple functions combined in one phase would create new options for high energy storage capacitors, microactuators, pyroelectric safety sensors, cooling devices, and pulsed power generators and so on, as well as great opportunities for generating new electronic devices with active magnetoelectric coupling effects.

Magnetoelectric Coupling Triggered by Noncollinear Magnetic Structure in M‐Type Hexaferrite

Direct magnetoelectric (ME) coupling between magnetic and ferroelectric orders, which can be realized in spiral magnets, is vital in technological applications of multifunctional materials. Multisusceptible BaFe 12 O 19 is noteworthy for its excellent magnetic, dielectric properties and thus the application in high-density information storage, while its collinear spin structure limits the emergence of ferroelectrics and ME coupling. In this work, nonzero Dzyaloshinskii-Moriya (DM) interaction is created by partial substitution of the spin-down Fe 3+ sites to induce conical spin structure in BaFe 12 O 19 . Larger In 3+ ions are introduced and prefer to occupy the spin-down 4f 1 and 4f 2 lattice sites. The evolution of magnetization versus temperature adduces evidence of conical magnetic structure. As a result, direct ME and magnetodielectric coupling are obtained in In-doped BaFe 12 O 19ceramics. An interlayer DM interaction model is built to discuss the intrinsic relationship among crystal structure, noncollinear magnetic structure, and ionic substitution. Moreover, BaZn 0.9 Zr 0.9 Fe 10.2 O 19 ceramics are also prepared, and exhibit noncollinear magnetic structure and direct ME coupling since Zn 2+ and Zr 4+ also possess larger radii than Fe 3+ and prefer to enter the spin-down sites. The present result provides a feasible avenue to develop multiferroic and magnetoelectric coupling in ubiquitous M-type hexaferrite.
