Monitoring the Velocity of Domain Wall Motion in Magnetic Microwires

Sensors
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.

Spiral Annealing of Magnetic Microwires. [PDF]

Sensors (Basel)
A preprocessing technique named “spiral annealing” was applied for the first time to magnetic microwires. In this process, the sample was arranged in a flat spiral shape during annealing, and subsequent measurements were conducted on the unbent sample with the induced stress distribution along and transverse to the sample.
