Sources of Magnetic Anisotropy
There are several sources of magnetic anisotropy:
- Magnetocrystalline anisotropy: the atomic structure of a crystal introduces preferential directions for the magnetisation.
- Shape anisotropy: when a particle is not perfectly spherical, the demagnetizing field will not be equal for all directions, creating one or more easy axes.
- Magnetoelastic anisotropy: tension may alter magnetic behaviour, leading to magnetic anisotropy.
- Exchange anisotropy: a relatively new type that occurs when antiferromagnetic and ferromagnetic materials interact.

Famous quotes containing the words sources of, sources and/or magnetic:
“My profession brought me in contact with various minds. Earnest, serious discussion on the condition of woman enlivened my business room; failures of banks, no dividends from railroads, defalcations of all kinds, public and private, widows and orphans and unmarried women beggared by the dishonesty, or the mismanagement of men, were fruitful sources of conversation; confidence in man as a protector was evidently losing ground, and women were beginning to see that they must protect themselves.”
—Harriot K. Hunt (1805–1875)
“I count him a great man who inhabits a higher sphere of thought, into which other men rise with labor and difficulty; he has but to open his eyes to see things in a true light, and in large relations; whilst they must make painful corrections, and keep a vigilant eye on many sources of error.”
—Ralph Waldo Emerson (1803–1882)
“We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.”
—Henry David Thoreau (1817–1862)
