“…We measured the DW velocity using modified SixtusTonks-like experiments described elsewhere [18,22,23]. 3 pick-up coils, mounted along the microwire and placed inside the long solenoid allowed to measure the velocity of propagating DW [18,22,23].…”

“…3 pick-up coils, mounted along the microwire and placed inside the long solenoid allowed to measure the velocity of propagating DW [18,22,23]. The electromotive force (emf ) sharp peaks from the 3 pick-up coils detected by the digital oscilloscope upon passing the propagating wall allowed estimation of the DW velocity as:…”

“…In the case of cylindrical amorphous microwires exhibiting spontaneous magnetic bistability the DW speed above 1 km/s can be easily achieved [18,22,23]. Aforementioned magnetic bistability is characterized by squired hysteresis loops related to a large and single Barkhausen jump within single domain axially magnetized inner core of wire [18,22,23]. Consequently studies of single DW propagation in amorphous glass-coated microwires are quite important for understanding of the ways to enhance the DW velocity in other materials.…”

We present an overview of the factors affecting soft magnetic properties, fast domain wall propagation and giant magnetoimpedance (GMI) effect in thin amorphous wires. The magnetoelastic anisotropy is one of the most important parameters that determine the magnetic properties of glass-coated microwires and therefore annealing can be very effective for manipulation the magnetic properties of amorphous ferromagnetic glass-coated microwires. Increasing of DW velocity in Fe-rich and Fe-Ni based (low Ni content) microwires is achieved after annealing. After heat treatment of Co-rich microwires we can observe transformation of inclined hysteresis loops to rectangular and coexistence of fast magnetization switching and GMI effect in the same sample. On the other hand stress annealing of Fe-and Co-rich microwires allows achievement of considerable magnetic softening and GMI effect enhancement.

Abstract-The possible types of transition structures that can arise between the regions of vortex asymmetric domain walls that exist in magnetically uniaxial permalloy films with in plane anisotropy have been studied by the method of three dimensional computer simulation of the magnetization behavior. It has been estab lished that, along with the previously found structures of vertical Bloch lines (VBLs), other types of structures can exist, namely, singular (Bloch) points and clusters that consist of VBLs and Bloch points. Spatial config urations and topological characteristics of transition structures have been calculated numerically.

Domain Wall Dynamics in Amorphous Ferromagnetic Wire with Small Helical Anisotropy

Dynamics of the domain wall between circular magnetic domains in amorphous ferromagnetic Co68.2Fe4.3Si12.5B15 wire was studied in a small region around the domain wall equilibrium position in an inhomogeneous magnetic field. The wire was prepared using the in-rotating-water-quenching technique. Small helical anisotropy was induced in the wire by current annealing and simultaneous application of tensile stress and torsion. The inhomogeneous magnetic field acted on domain wall by restoring force directly proportional to the displacement of the domain wall from its equilibrium position. Domain wall position was monitored by circular magnetic flux measurements from which it results that domain wall motion can be modeled by the motion of a very strongly damped pendulum. The value of domain wall mobility obtained from these experiments is in good agreement with the values calculated and measured for domain wall driven by a constant magnetic field.
