“…Melt extraction technique allows the fabrication of thinner (roughly 30-60 μm in diameter) microwires. Additionally the diameter of wires produced by in-rotating-water technique can be reduced using either cold drawing or warm drawing [51][52][53][54][55]. The thinnest cast microwires can be produced using Taylor-Ulitovsky technique [21,26,56].…”

First amorphous materials using rapid quenching from the liquid state were prepared nearly 50 years ago [1][2][3][4]. Development of the rapid-quenching technique allowed obtaining of new materials with metastable crystalline, amorphous, nanocrystalline, granular structures with a new combination of physical properties (mechanical, magnetic, electrochemical, etc.) and opening of new fields of research in material science, magnetism, and technology. During the next years, few rapidquenching technologies allowing preparation of different types of rapidly quenched materials have been developed. At the beginning most attention has been paid to studies of planar rapidly quenched materials: rapidly quenched ribbons produced by quenching on the drum [4][5][6].Excellent magnetic softness of amorphous materials obtained by the meltspinning technique has attracted considerable attention, making them very attractive in potential applications in recording head and microtransformer industries. Such magnetic softness originates from the absence of magnetocrystalline anisotropy in these alloys [6].Further development of the rapidly quenching fabrication techniques allowed preparation of rapidly materials with cylindrical symmetry: rapidly quenched wires [7][8][9][10]. Amorphous wires, typically around 125 μm in diameter, obtained by the so-called in-rotating-water quenching technique, have been firstly introduced in 1980.The magnetostrictive compositions exhibit rectangular hysteresis loop, while the best magnetic softness is observed for the nearly zero magnetostriction composition.

“…The market is forecasting the further-reduced minimum feature size and fabrication cost, while increasing density of devices in the applications. Therefore, the magnetic sensor technology has been driven by the needs for improved sensitivity, smaller size, quicker response, and lower prices [16][17][18][19][20]. In this context, recently developed magnetic sensors utilizing giant magnetoimpedance (GMI) effect, so-called GMI sensors [21,22], are of great interest, because of their high sensitivity, high flexibility, and cost-effectiveness.…”

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.

Off‐diagonal component of magneto‐impedance tensor with pulse excitation is very promising for high sensitivity magnetic field sensor applications. We report novel results on studies of off‐diagonal MI effect and magnetic properties in amorphous glass‐coated microwires with nearly‐zero and negative magnetostriction constant and metallic nucleus diameter ranging between 6 μm and 10 μm. Off‐diagonal impedance tensor ζφz (Hex) has been investigated in ultra‐thin amorphous glass‐coated microwires in as‐cast state and after Joule heating treatment. (© 2008 WILEY‐VCH Verlag GmbH & Co.
