Giant magnetoelectric effect in vacuum

, 2022
Art. 232905, 4 S.Magnetoelectric (ME) thin film cantilever type sensors made of AlN and FeCoSiB are operated in vacuum, reducing air damping and thus increasing the ME coefficient and improving the limit of detection (LOD) for ac-magnetic fields ...

A Feedback Method to Improve the Dynamic Range and the Linearity of Magnetoimpedance Magnetic Sensor

Journal of Sensors, Volume 2019, Issue 1, 2019., 2019
We developed a high‐sensitivity magnetoimpedance magnetic field sensor using a FeCoSiB amorphous wire and a coil wound around it. The amorphous wire had the diameter of 0.1 mm and the length of 5 mm. The magnetic field resolution of about 20 pT/√Hz was achieved.

X-RAY STRUCTURE ANALYSIS OF AMORPHOUS ALLOYS FeCoSiB, FeSiB AND FeB

Acta Physica Sinica, 1980
In this work, the structures of the amorphous alloys Fe5Co70Si15B10,Fe78Si1OB12 and Fe80B20 were analysed by X-ray diffraction method. From the diffraction intensity data the structure factors and radial distribution functions (RDF) of these materials were calculated.In order to obtain partial radial distribution functions (PRDF) of the binary alloy ...

Recent Advances of Amorphous Wire CMOS IC Magneto‐Impedance Sensors: Innovative High‐Performance Micromagnetic Sensor Chip

Journal of Sensors, Volume 2015, Issue 1, 2015., 2015
We analyzed and organized the reasons why the amorphous wire CMOS IC magneto‐impedance sensor (MI sensor) has rapidly been mass‐produced as the electronic compass chips for the smart phones, mobile phones, and the wrist watches. Comprehensive advantageous features regarding six terms of (1) microsizing and ultralow power consumption, (2) high linearity

Strain‐Driven Electric Field Control of Magnetization in FeGa/PMN‐PT

Advanced Electronic Materials, Volume 11, Issue 20, December 3, 2025.
Controlling magnetization using only electric fields is crucial to achieve low‐power, memory and spintronic devices. By controlling the ferroelectric polarization rotation of PMN‐PT interfaced with a FeGa thin film, distinct strain levels are generated.

High Magnetic Sensitivity at the Coercive Field Induced by Shear Horizontal SAW in Polycrystalline FeGa Films

Advanced Materials Technologies, Volume 10, Issue 18, September 18, 2025.
A theoretical framework links stress‐induced changes in the Young's modulus of Fe₇₂Ga₂₈ layers to their magnetization dynamics under SH‐SAW excitation. This interaction produces a sharp sensor response near the coercive field, highlighting FeGa's magnetoelastic sensitivity.

Low‐Noise, Unbiased Ferromagnetic‐Resonance‐Driven Thin‐Film Integrated Giant Magnetoimpedance Sensors

Advanced Materials Technologies, Volume 10, Issue 14, July 22, 2025.
Utilizing a novel (Ni81Fe19/Ti)4/Cu/(Ni81Fe19/Ti)4 thin‐film multilayer with low coercive field, low damping and a superior GMI ratio, a compact, low‐noise unbiased FMR‐driven integrated GMI sensor with a superior magnetic noise performance of ≈100 pT/√Hz is first demonstrated, owing to reduced phase noise from well‐defined aligned magnetic domains and

Modeling of High‐Sensitivity SAW Magnetic Field Sensors with Au‐SiO2 Phononic Crystals

Advanced Sensor Research, Volume 4, Issue 5, May 2025.
This paper presents a highly sensitive surface acoustic wave (SAW) magnetic field sensor that incorporates phononic crystals (PnCs) with gold pillars in a SiO2 guiding layer. By integrating the PnC into the guiding layer, the design enhances the interaction between SAWs and the magnetostrictive material, achieving improved sensitivity through resonance
