Magnetically Boosted Water‐Splitting Performance in Metallic Glasses

open access: yesAdvanced Science, EarlyView.
A strategy for boosting water electrolysis efficiency using ultralow magnetic fields on soft‐magnetic MG wires is reported. Ni40Fe40P20 metallic glass exhibits superior overall water‐splitting performance (1.51 V @ 1000 mA cm−2) at 100 Oe, enabled by spin polarization in periodic surface magnetic domains to enhance orbital hybridization and net spin ...

Effect of Adding Co on Crystallization Behavior and Magnetoimpedance Effect of Amorphous/Nanocrystalline FeCuNbSiB Alloy Strips

open access: yesAdvances in Condensed Matter Physics, Volume 2019, Issue 1, 2019., 2019
After one of the B atoms in Fe73.5Cu1Nb3Si13.5B9 alloy was replaced by both 0.7 Si and 0.3 Co, Fe73.5Co0.3Cu1Nb3Si14.2B8 alloy ribbons were prepared by single roll fast quenching method. The obtained alloy ribbons were subsequently wound into ring magnetic cores, and then these magnetic cores were annealed at different temperatures in air.

Operation Regimes and Design Principles of Delta‐E Effect Sensors

open access: yesAdvanced Sensor Research, Volume 5, Issue 4, April 2026.
Delta‐E effect magnetoelectric sensors enable the detection of weak magnetic fields, yet performance optimization remains nontrivial due to coupled magnetic, mechanical, and electronic losses. A systematic study of 24 miniaturized MEMS devices with different geometries reveals three excitation‐dependent regimes: electronic‐noise, magnetic‐noise, and ...

Magnetoimpedance Effect in CoFeMoSiB As‐Quenched and Surface Modified Amorphous Ribbons in the Presence of Igon Oxide Nanoparticles of Water‐Based Ferrofluid

open access: yesJournal of Sensors, Volume 2017, Issue 1, 2017., 2017
Giant magnetoimpedance (GMI) has been proposed as a powerful technique for biosensing. In GMI biosensors based on the magnetic label detection the change of the impedance of sensitive element under the application of an external magnetic field was analyzed in the presence of magnetic nanoparticles in a test solution.

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

open access: yesJournal 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
