Amorphous glass-coated microwires are magnetic materials well-known by very high domain wall velocities reaching up to 15 km/s. In the previous works was shown, that domain wall dynamics in microwires could be effectively tuned by biasing of additional anisotropies. Here we show the possibility of inducing anisotropy to the microwires. Thermal annealing at 300°C in perpendicular field speed... View full abstract»

Magnetic non destructive methods are frequently used in the industries of steel since magnetic behavior demonstrates a good sensitivity to the microstructural and/or mechanical changes. Magnetic behavior is especially sensitive to plastic straining that occurs for example with the manufacturing of materials (cutting, punching). Evaluating the state of a material from a measurement requires a model... View full abstract»
