Advances in Magnetic Field Sensors [PDF]

, 2010
The most important milestone in the field of magnetic sensors was when AMR sensors started to replace Hall sensors in many applications where the greater sensitivity of AMRs was an advantage. GMR and SDT sensors finally found applications. We also review

Magnetization and Giant Magnetoimpedance Effect of Co‐Rich Microwires under Different Driven Currents

Journal of Sensors, Volume 2016, Issue 1, 2016., 2016
Co68.25Fe4.5Si12.25B15 amorphous microwires with a diameter of 34 μm were prepared via the melt extraction method. The dependency of AC driving current Iac and frequency on giant magnetoimpedance (GMI) effect and magnetization were investigated using a 4294A impedance analyzer and the transverse Kerr effect. The GMI effect was analyzed when Iac changed

Optimization of the high-frequency magnetoimpedance response in melt-extracted Co-rich microwires through novel multiple-step Joule heating

Journal of Science: Advanced Materials and Devices, 2021
The optimization of the high frequency giant magnetoimpedance (GMI) effect and its magnetic field sensitivity in melt-extracted Co69.25Fe4.25Si13B12.5Nb1 amorphous microwires was systematically studied through a multi-step Joule annealing (MSA) technique.

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

Torsion Dependence of Domain Transition and MI Effect of Melt‐Extracted Co68.15Fe4.35Si12.25B13.25Nb1Cu1 Microwires

Advances in Materials Science and Engineering, Volume 2015, Issue 1, 2015., 2015
We present the torsional stress induced magnetoimpedance (MI) effect and surface domain structure evolution of magnetostrictive melt‐extracted Co68.15Fe4.35Si12.25B13.25Nb1Cu1 microwires. Experimental results indicate that the surface domain structures observed by magnetic force microscope (MFM) transform from the weak circumferential domain of as‐cast

Laser‐Guided Self‐Assembly of Thin Films into Micro‐Rolls

Advanced Functional Materials, Volume 34, Issue 19, May 10, 2024.
Combining laser scribing techniques and strain engineering techniques, a laser‐guided self‐assembly strategy is developed to manufacture 3D micro‐rolls from thin films. This dry‐release strategy is highly scalable and viable in the atmosphere, and achieves precise control of self‐assembly behavior (including self‐rolling areas, curvatures, orientations,
