“…Magnetic sensors based on the magnetoimpedance effect have potential for application in weak magnetic field detection, given their high precision and small size. Since Mohri discovered the magnetoimpedance effect in soft magnetic CoFeSiB amorphous wires [1], the sensors-based magnetoimpedance (MI) effect has been studied widely for over two decades [2,3,4,5,6,7]. This MI effect arises from a combination of a skin effect and a strong field dependence of the circumferential magnetic permeability associated with circular domain wall movements [8].…”

The purpose of this study was to measure the low-frequency noise and basic performance of a commercial magnetoimpedance (MI) sensor at sub-millihertz frequencies for use in space missions. Normally, space missions require measuring very weak magnetic fields with a long integration time, such as the space gravitational wave detection mission requiring sub-millihertz frequencies. We set up a platform for measuring the performance on this MI sensor, including low-frequency noise, measurement limit, linearity, and temperature stability. The results show that the low-frequency noise of the MI sensor is below 10 nT/√Hz at 1 mHz and below 100 nT/√Hz at 0.1 mHz; its measurement limit is 600 pT. The MI sensor is characterized by high precision, small size, and low noise, demonstrating considerable potential for application in magnetically sensitive experiments requiring long integration time. This is an effect way to solve the problem that there is on one suitable magnetic sensor at space magnetic field detection, but the sensor requires improvements in temperature stability.

“…It has attracted much interest due to its stability and small size for potential applications in highly sensitive magnetic sensors. Many researchers have investigated GMI effect in different soft magnetic materials including homogeneous and composite materials [2][3][4][5][6]. It was found that GMI origins from classical electrodynamics, which relates to inductive effect, skin effect and ferromagnetic resonance.…”

Giant Magneto-impedance Effect in Composite Wires with Different Core Layer

Composite structure materials were potential sensing elements for magnetic sensors due to Giant magnetoimpedance (GMI) effect. Two kinds of composite wires with different magnetic/non-magnetic structures were fabricated by using electroless deposition methods and the magnetoimpedance properties were investigated. The maximum GMI ratio of 114% was acquired at 60 MHz in the composite wires with a ferromagnetic core, whereas, 116% of maximum GMI ratio was found in the composite wires with a conductive core at low frequency of 600 kHz. These results exhibit that the GMI ratio reaches the maximum when magnetoresistance ratio ΔR/R and magnetoinductance ratio ΔX/X make the comparative contributions to the total magnetoimpedance (MI). The obvious GMI effect obtained in the composite wires with conductive core frequency may provide a candidate for applications in magnetic sensors, especially at low frequencies.

“…Some prototype sensors employing these materials as sensing elements, i.e., magnetic field sensors [46][47][48][49][50], current sensors [51,52], position sensors [53,54], stress sensors [55,56], torque sensor [57], biosensors [58][59][60][61][62][63], were proposed and successfully developed. The current progress of GMI is thrusted toward the increase of magnetic-field sensitivity and the optimization of the signal-to-noise ratio in the GMI sensor devices [64,65].…”

In recent years, all modern vehicles and transport means use a vast variety of sensors and transducers. The operation of all medical instruments is also based on sensors and transducers. Industry is also employing more and more transducers for the monitoring and control of production lines. Therefore, the sensing technology has been driven by the increasing needs for enhanced sensitivity, improved stability, high reliability, and lower costs. For this purpose, we have proposed and developed novel two LC resonant-type magnetoimpedance (LCMI) sensor devices utilizing soft magnetic microwires as a sensing element, giving an emphasis on the use of resonance effect from LCcomponents and the rapid permeability change of the magnetic microwires to significantly improve the sensitivity performance of sensors. This article aims to provide a comprehensive analysis of the design and operation of these devices. After a description of magnetic core materials, circuit designs and fabrication techniques is given, the details of all experimental measurements are presented. The characterizations of constructed LCMI sensor devices are systematically analyzed, and the physical origins of magneto-resonant phenomena, field, and frequency dependences in these LCMI sensor devices are addressed. Influences of processing parameters on the sensing characteristics of LCMI sensors are also discussed. This enables the optimal conditions to fabricate high-performance magnetic sensing devices.
