If there is more than one magnetic domain, the transition between one domain and its neighbor involves a rotation of the magnetization to form a domain wall.

These are very different from conventional magnets that store information at a magnetic domain level and theoretically could provide a far denser storage medium than conventional magnets.
43.
By 2004, Bajorek said, the industry will need to begin stacking the tiny magnetic domains perpendicularly to squeeze them more tightly onto the surface of the disk media.

FXS can be used for the determination of ( large ) macromolecular structures, but has also found applications in the characterization of metallic nanostructures, magnetic domains and colloids.
45.
Discovered by German physicist Heinrich Barkhausen in 1919, it is caused by rapid changes of size of magnetic domains ( similarly magnetically oriented atoms in ferromagnetic materials ).
46.
This field tends to rotate the magnetization in a way that reduces the total moment of the magnet, and in larger magnets the magnetization is organized in magnetic domains.
47.
Due to the polycrystalline nature of the magnetic material each of these magnetic regions is composed of a few hundred magnetic perpendicular to allow for closer magnetic domain spacing.
48.
This means that the magnetic domains cannot grow or shrink to form spikes, and therefore the transition width will be on the order of the diameter of the grains.
49.
Contrast due to polarization is invaluable in distinguishing fluorescence and diffraction signals and imaging magnetic domain structure by using techniques such as linear and circular dichroism and magnetic diffraction.
50.
Magnetic domains written too densely together to a weakly magnetisable material will degrade over time due to rotation of the magnetic moment one or more domains to cancel out these forces.
