Glass-coated microwires are composite materials that consist of a metallic nucleus covered by glass shielding. They are prepared by drawing and rapid quenching of molten alloys and glass.
They have unique properties in terms of the magnetization process and mechanical behavior, making them ideal for sensing various physical quantities in engineering applications.
Magnetic properties stem mainly from magnetoelastic interaction—the interaction of magnetic moments with a distribution of mechanical stresses induced during production.
