Magnetoinductive e ects in ferromagnetic conductors can be used for various sensors. Although the principle has been known for a long time, the usefulness of these e ects for practical applications was recognized recently, and intensive investigations began. Magnetoinductive e ects are related to magnetization of a magnetic conductor (wire, strip, thin lm, etc.) by a magnetic eld, which is prod...
Giant Magnetoimpedance (GMI) sensor is the hot research topics in sensor engineering. In this paper we setup a double channel acquisition system for MGG signal. Then FastICA algorithm is applied in the raw data and We get the spectrum after ICA processing. The results show that ICA is powerful tool for MGG signal processing to separate the noise signal. Introduction Recently giant Magnetoimpeda...
The giant magnetoimpedance of an 8.5 m glass-covered amorphous microwire was investigated in the frequency range of 10 MHz–3.5 GHz. It was found that when the exciting microwave current exceeds some threshold value, a periodic fine structure appears in the frequency dependence of the complex impedance. The appearance of this nonlinear phenomenon is interpreted to be a consequence of the paramet...
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...
