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

open access: yesAdvanced 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

Magnetoimpedance effects in a CoNiFe nanowire array

open access: yesJournal of Alloys and Compounds, 2013
Abstract This report describes the growth of CoNiFe nanowires into highly ordered porous anodic alumina oxide (AAO) templates by DC electrodeposition at a pH value of 2.6. Scanning electron microscopy (SEM) observations revealed that the wires have diameters of approximately 270–290 nm and a length of 25 μm. The energy dispersive X-ray (EDX) analysis

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

open access: yesJournal 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.

Tunable asymmetric magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films

open access: yes, 2014
We investigate the magnetization dynamics through the magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films. We observe that the magnetoimpedance response is dependent on the thickness of the non-magnetic Cu spacer material, a fact associated to the ...

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

open access: yesAdvanced 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,
