Magnetic field driven domain-wall propagation in magnetic nanowires

Annals of Physics, 2009
The mechanism of magnetic field induced magnetic domain-wall (DW) propagation in a nanowire is revealed: A static DW cannot exist in a homogeneous magnetic nanowire when an external magnetic field is applied. Thus, a DW must vary with time under a static

Propagation of a Magnetic Domain Wall in a Submicrometer Magnetic Wire

Science, 1999
The motion of a magnetic domain wall in a submicrometer magnetic wire was detected by use of the giant magnetoresistance effect. Magnetization reversal in a submicrometer magnetic wire takes place by the propagation of a magnetic domain wall, which can be treated as a “particle.” The propagation velocity of the magnetic domain wall was determined as a ...

Automotive domain wall propagation in ferromagnetic rings

2015 IEEE Magnetics Conference (INTERMAG), 2015
Automotive domain wall propagation is a self-propelling motion utilizing the energy stored in a particular energy reservoir of the spin structure to speed up domain wall beyond its equilibrium value given by external driving force and damping. Such a concept of DW motion is of great interest due to recent development of spintronic devices based on ...

Domain wall propagation in Fe-rich microwires

Physica B: Condensed Matter, 2008
We studied the velocity of domain wall propagation, v, of Fe 69 Si 10 B 15 C 6 with different metallic nucleus diameter, d, and different total diameter, D (d = 14 μm, D = 33 μm and d= 18 μm, D = 23.4μm, respectively) in the temperature range between 78 and 300K and at different frequencies of applied magnetic field.

Avalanches as propagating domain walls in a micromagnetic model

Physica D: Nonlinear Phenomena, 1998
Abstract The ideas of self-organized criticality can be partially applied to describe collective demagnetization process. The basic point to proceed with this analysis is the identification of propagating domain walls with avalanches. We study the avalanche size distributions in a micromagnetic model describing a textured polycrystal.

Experimental detection of domain wall propagation above the Walker field

Journal of Physics: Condensed Matter, 2011
The domain wall (DW) velocity above the Walker field drops abruptly with increasing magnetic field, because of the so-called Walker breakdown, where the DW moves with a precessional mode. On applying the higher field, the DW velocity again starts to increase gradually.

Dynamics of field-driven domain-wall propagation in ferromagnetic nanowires

Nature Materials, 2005
Ferromagnetic nanowires are likely to play an important role in future spintronic devices. Magnetic domain walls, which separate regions of opposing magnetization in a nanowire, can be manipulated and used to encode information for storage or to perform logic operations.

Domain Wall Propagation in Nanocrystalline Glass-Coated Microwires

IEEE Transactions on Magnetics, 2009
The characteristics of domain wall propagation in Fe73.5Cu1Nb3Si13.5B9 amorphous and nanocrystalline glass-coated microwires are investigated in order to determine the changes induced by structural transformation in wall velocity and mobility. An improved method for sensing the wall presence and direction, and for measuring its velocity, is also ...

Domain wall phenomena in bubble propagation layers

Journal of Magnetism and Magnetic Materials, 1983
Abstract The role of domain walls in bubble propagation layers is reviewed. Conventional permalloy overlay structures of typically 0.4–0.5 μm thickness show stray field free domain wall structures. These walls are very wide and mobile. It is concluded that wall pinning and irreversibilities are primarily connected with Bloch lines and other ...

Domain wall injection and propagation in planar Permalloy nanowires

Journal of Applied Physics, 2002
We have used high-sensitivity magneto-optics to study the magnetic switching of a single 20 μm long, 100 nm wide, 5 nm thick planar Permalloy wire made by focused ion beam milling. It is found that the switching field of the wire can be dramatically reduced by the addition of a large end pad to the wire, which serves as a domain wall injector.
