Summary: This study reports the self-biased, in-plane 180 degrees magnetization switching of FeGaB nanomagnets on PMN-PT piezoelectric substrate, achieved by varying the thickness of nanomagnets with different aspect ratio. The research also reveals that in-plane 180 degrees magnetization switching for larger aspect ratio nanomagnets is limited due to the maximum achievable stress from the piezoelectric layer. The underlying physics, including the relationship between the critical switching time and energy, is elucidated using finite difference method (FDM) micromagnetic model coupled with elastodynamic and electrostatic conditions.

Summary: In a quasi-two-dimensional planar antiferromagnet BaNi2(PO4)(2), a long-range antiferromagnetic ordering of Ni2+ ions at T-N = 24 K was observed. Interestingly, an electric polarization proportional to the applied magnetic fields was induced at T-N, demonstrating the linear magnetoelectric effect with a coupling coefficient of 1.67 ps/m in BaNi2(PO4)(2). The magnetic symmetry associated with the magnetoelectric effect (1) over bar' allows all tensor elements of the magnetoelectric susceptibility.

Summary: Measurement of 3D vector magnetic field is vital for magnetic navigation, biomedical diagnosis, and microimaging. Traditional 3D magnetic sensors have limitations in size and spatial resolution, but recent spin orbit torque sensors based on ferromagnetic/heavy-metal heterostructures can detect magnetic field components individually. However, their practical application is hindered by large driving current density and complex driving procedure. In this study, 3D magnetic sensors with significantly reduced driving current density are reported, along with a record-high sensitivity and the ability to work with ultralow driving current density.

Summary: Magnetoelectric (ME) sensors based on piezoelectric/ferromagnetic composites have been extensively investigated for their resonance-enhanced ME coupling effect and high sensitivity for magnetic field. However, their sensitivity drops rapidly away from resonance, making them unsuitable for low-frequency applications. In this work, we study the optimized amplitude and frequency of the modulation field, which significantly improve the sensitivity at low frequency without increasing the noise level. A magnetic field of 200 pT is detected at 10 Hz with a near-flat frequency response in the range of 1-100 Hz, showing promising potential for low-frequency applications in smart grid and renewable energy.

Summary: To achieve compact and lightweight power conversion devices, MnZn ferrite doped with high-valent Sn4+ ions is used to manipulate electromagnetic properties and suppress high-frequency core losses. The Sn4+ ions mainly occupy grain boundaries rather than dissolving into the lattice, significantly impacting the electromagnetic properties. With increasing Sn substitution, initial permeability and saturation induction decrease monotonically. A Sn substitution content of 0.003 reduces core losses to 457 kW m(-3) at 3 MHz, 30 mT, and 25 degrees C, effectively suppressing eddy current loss and residual loss. The sample with Sn content of 0.003 demonstrates excellent overall electromagnetic properties, making it potentially useful in high-frequency transformers, converters, and power sources.

Summary: This study investigates the relationship between domain morphology, dynamic magnetization behavior, and high-frequency core losses in MnZn ferrites by producing MnZn ferrites with different grain sizes through changing the sintering temperature. The results show that when the grain size approaches the critical size, the residual loss is effectively reduced, while an increase in grain size leads to a sharp increase in residual loss.
