Modeling of asymmetric giant magnetoimpedance in amorphous ribbons with a surface crystalline layer

Gamma Irradiation Effect on Asymmetric Giant Magnetoimpedance of Co68.15Fe4.35Si12.5B15 Amorphous Alloy

The giant magneto impedance (GMI) effect is a large variation in the electrical impedance of a magnetic conductor when subjected to a static magnetic field. The sensitivity to the direction (AGMI) and magnitude of applied  magnetic field    and also linearity levels   of this  effect are three important parameters in magnetic sensors application. A suitable annealing procedure can be used to ac...

Giant magnetoimpedance and field sensitivity in amorphous and nanocrystalline (Co1â‹TMxFex)89Zr7B4 (xâ•›=â•›0, 0.025, 0.05, 0.1) ribbons

Introducing and investigating structural and magnetic properties of ribbons Co68.5-xFe4WxSi16.5B11 (x = 0.8, 2) in amorphous and crystalline states

In this study, for the first time, cobalt base ribbons were made by adding two different amounts of tungsten with Co67.7Fe4W0.8Si16.5B11 and Co66.5Fe4W2 Si16.5B11 compounds by melt spinning in the water. The pattern of  X-ray diffraction taken from these ribbons shows that these magnetic ribbons are amorphous. By using thermal analysis curves, taken from the ribbons, crystallization temperature...

Longitudinally driven giant magnetoimpedance effect in stress-annealed Fe-based nanocrystalline ribbons

A high-frequency longitudinally driven giant magnetoimpedance ~GMI! effect has been measured in stress-annealed Fe73Cu1Nb1.5V2Si13.5B9 nanocrystalline ribbons. Based on how the impedance phase varies with the external magnetic field, it becomes clear that the imaginary part of the complex permeability, m9, which is related to magnetic losses, plays an important role in the high-frequency longit...

Nanocrystallization in Co67Cr7Fe4Si8B14 Amorphous Alloy Ribbons

The nanocrystallization of Co67Fe4Cr7Si8B14 amorphous ribbons which prepared by planar flow melt spinning process (PFMS) was investigated. Crystallization of the ribbons was studied by differential thermal analysis (DTA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The DTA result of amorphous ribbon at heating rate of 10˚C/min showedoccurrence of phase transitions in two...
