Reverse domain propagation in Fe-Co base amorphous wires.

Domain Wall Propagation in Bistable Amorphous Microwires

Tendency on miniaturization of the modern magnetic sensors and devices stimulates development of such magnetic materials with reduced dimensionality. Therefore magnetic materials with outstanding magnetic characteristics and reduced dimensionality recently gained much attention. Consequently thin wire with reduced geometrical dimensions (of order of 1-30 μm in diameter) gained importance within...

Studies of domain dynamics in amorphous Dy/Fe multilayers

Composition dependence of field induced anisotropy in ferromagnetic „Co,Fe...89Zr7B4 and „Co,Fe...88Zr7B4Cu1 amorphous and nanocrystalline ribbons

The composition dependence of field induced anisotropy KU of field annealed soft ferromagnetic Co1−xFex 89Zr7B4 and Co1−xFex 88Zr7B4Cu1 amorphous and amorphous/nanocrystalline “nanocomposite” melt spun ribbons is investigated. With the exception of the highest Co-containing alloys x 0.10 , the observations are discussed in terms of a superposition of directional pair ordering of Fe,Co atoms and...

Negative Magnetoresistance in Amorphous Indium Oxide Wires

We study magneto-transport properties of several amorphous Indium oxide nanowires of different widths. The wires show superconducting transition at zero magnetic field, but, there exist a finite resistance at the lowest temperature. The R(T) broadening was explained by available phase slip models. At low field, and far below the superconducting critical temperature, the wires with diameter equa...

Fermions and Bosons in Superconducting Amorphous Wires

We discuss the destruction of superconductivity in quasi-one-dimensional systems due to the interplay between disorder and Coulomb repulsion. We argue that to understand the behavior of the system one has to study both fermionic and bosonic mechanisms of suppression of superconductivity. The former describes reduction in the mean field critical temperature Tc, while the latter refers to thermal...
