| 11. | The small size of nanomagnets prevents the formation of magnetic domains ( see single domain ( magnetic ) ).
|
| 12. | A "'magnetic domain "'is a region within a magnetic material in which the magnetization is in a uniform direction.
|
| 13. | The size range is bounded below by the transition to superparamagnetism and above by the formation of multiple magnetic domains.
|
| 14. | Magnetic domains form in materials which have magnetic ordering; that is, their dipoles spontaneously align due to the exchange interaction.
|
| 15. | His own early work on magnetic domain theory, he said, was something " we were doing for pure curiosity ."
|
| 16. | On a lengthscale that is less than a single magnetic domain size, the interaction between atomic spins realigns the magnetic moments.
|
| 17. | They stick together and align themselves into small regions of more or less uniform alignment called magnetic domains or Weiss domains.
|
| 18. | This is because the internal magnetic domains of the material align with each other to greatly enhance the magnetic flux density.
|
| 19. | For reliable storage of data, the recording material needs to resist self-demagnetisation, which occurs when the magnetic domains repel each other.
|
| 20. | Magnetic domains can be observed with a magnetic force microscope to reveal magnetic domain boundaries that resemble white lines in the sketch.
