“…The process of magnetization reversal in Fe-rich microwires takes place when a single DW is detached from one of the closure end domains and is subsequently displaced along the microwire [ 20 , 26 , 48 , 49 ]. On the other hand, the magnetization reversal process in Co-rich microwires is characterized by the rotation of magnetization.…”

“…The Co-rich microwire was situated in close proximity to the surface of the long Fe-rich microwire, as well as in the space between the secondary coils 2 and 3. The black line (Figure 3) represents the velocity that was measured between coils 1 and 2, whereas The process of magnetization reversal in Fe-rich microwires takes place when a single DW is detached from one of the closure end domains and is subsequently displaced along the microwire [20,26,48,49].

“…The observation of rapid single-domain wall (DW) propagation in magnetic wires has garnered significant attention from the perspective of fundamental physics. This includes investigating the origins of DW nucleation and propagation fields, as well as the remarkably high DW velocities ( v ) and DW mobility ( S ) [ 1 , 20 , 25 , 26 , 27 , 28 , 29 , 30 ]. Conversely, various potential applications, such as racetrack memories, magnetic logic, and electronic surveillance, have been developed by leveraging the magnetic bistability of fast and controllable DW propagation [ 31 , 32 , 33 ].…”

An approach was proposed to control the displacement of domain walls in magnetic microwires, which are employed in magnetic sensors. The velocity of the domain wall can be altered by the interaction of two magnetic microwires of distinct types. Thorough investigations were conducted utilizing fluxmetric, Sixtus–Tonks, and magneto-optical techniques. The magneto-optical examinations revealed transformation in the surface structure of the domain wall and facilitated the determination of the mechanism of external influence on the movement of domain walls in magnetic microwires.

“…Thanks to the special design of these coils, it is possible to place them in the proximity of the sensing element and to sense the microwire response contactlessly. There is no necessity to place the inspected component into the cylindrical coil system, as is usually the case [42][43][44][45]. The measurement block diagram can be seen in Figure 3.…”

The development of non-destructive methods for material testing and diagnostics has been, in the last few decades, focused mainly on optical, infrared, thermography, ultrasonic, acoustic or X-ray principles. This article deals with the possibility of adaptation of magnetic sensors for the diagnostics of aircraft structures. The developed sensors are based on the enhanced induction method, allowing contactless diagnostics of the material structure. In the role of the sensing element, amorphous magnetic microwires were used. Thanks to their dimensions, microwires can either be placed on the material surface or be embedded directly into the composite material without structural violations. In the article, the measurement principles of the developed microwire-based tensile stress sensors, together with the experimental measurements with the sensors originally tested in the aircraft wing, are presented.
