Understanding of double-curvature shaped magnetoimpedance profiles in Joule-annealed and tensioned microwires at 8-12 GHz

, 2014
We have investigated for the first time the combined effect of current and stress on the GMI characteristics of vanishing-magnetostrictive Co-rich microwires at microwave frequency.

Surface Roughness-Controlled Superelastic Hysteresis in Shape Memory Microwires [PDF]

, 2014
Superelasticity in Cu–Zn–Al shape memory alloy microwires is studied as a function of surface roughness. Wires with a rough surface finish dissipate more than twice as much energy per unit volume during a superelastic cycle than do electropolished wires ...

The Effect of High-Temperature Annealing on the Magnetic and Structural Properties of (MnFePSi)-Based Glass-Coated Microwires

Crystals
In this paper, the impact of annealing at different temperatures (973 K, 1073 K, and 1123 K for 1 h) on the magnetic and microstructural properties of MnFePSi-based glass-coated microwires is studied.

Development of Co-Rich Microwires with Graded Magnetic Anisotropy

Sensors, 2021
In this paper, a gradual change in the hysteresis loop of Co-rich glass-coated microwire stress-annealed at variable temperature is observed. Such microwires annealed with a temperature gradient also present a variable squareness ratio and magnetic ...

Left-handed metacomposites containing carbon fibers and ferromagnetic microwires [PDF]

, 2017
We investigate the microwave behavior of polymer-based metacomposites containing ferromagnetic microwires and carbon fibers. A notable transmission window is observed from the metacomposite containing 3mm spaced parallel microwire array in 1-7 GHz ...

Ferromagnetic Wires Composite Media with Tunable Scattering Spectra at Microwaves

, 2006
We demonstrate composite media with ferromagnetic wires that exhibit a frequency region at the microwave regime with scattering spectra strongly dependent on an external magnetic field or stress.
