Magneto‐Ionic Devices With Polymer‐Based Electrolytes

Advanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Analysis of asymmetric property with DC bias current on thin-film magnetoimpedance element

AIP Advances, 2018
We theoretically analyzed the magnetoimpedance profile of a thin-film element with a DC bias current using the bias susceptibility theory and Maxwell’s equations. Although the analysis model predicts that an element with a rectangular cross section shows

Self‐Powered, Ultra‐Sensitive InGaAs/ITO Nanowire Radial Junction Infrared Photodiode for Low Flux Imaging at Room Temperature

Advanced Functional Materials, EarlyView.
This study reports a self‐powered InGaAs nanowire photodetector achieving single‐photon‐level sensitivity in the shortwave infrared at non‐cryogenic temperatures. The device demonstrates high‐speed imaging capabilities even under extremely low‐flux conditions.

Fabrication of FeSiBPNb amorphous powder cores with high DC-bias and excellent soft magnetic properties

, 2016
Fe-based amorphous magnetic alloy powders with a composition of (Fe0.76Si0.09B0.1P0.05)(99)Nb-1 were first prepared by water atomization, and then amorphous magnetic powder cores were produced from a mixture of the amorphous alloy powders with diameters ...

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

Advanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

Increased particle confinement with the use of external dc bias field in the CTX spheromak [PDF]

, 1985
Spheromaks are formed in a mesh flux conserver in the presence of an external dc bias field. The spheromaks remain stable to tilt instabilities with ratios of bias-to-spheromak flux of up to 47 +- 7%.
