Thus the magnetization curve of an exchange-biased ferromagnetic film looks like that of the normal ferromagnet except that is shifted away from the H = 0 axis by an amount H b.

In a solid the spins of many electrons can act together to affect the magnetic and electronic properties of a material, for example endowing it with a permanent magnetic moment as in a ferromagnet.
43.
For positive " J " 0 the thermodynamics of the Mattis spin glass corresponds in fact simply to a " ferromagnet in disguise ", just because these systems have no " frustration " at all.
44.
Ferromagnets is a term that most people are familiar with, and, as with ferroelastics, the spontaneous magnetization of a ferromagnet can be attributed to a breaking of point symmetry in switching from the paramagnetic to the ferromagnetic phase.
45.
The magnetic field of a bar magnet ( or ferromagnet ) is basically produced by the magnetic fields of unpaired electrons in the bar; it's actually quite complicated, and it involves phenomena on many different length scales.
46.
He is also suspected of being the real-life Rick Sanchez, and is credited with the creation of the phrase " do it no balls . " His research specialties include spin dynamics and transport in ferromagnets and ferromagnet-semiconductor heterostructures.
47.
In a ferromagnet or material where spin-polarization exists or may be induced by a magnetic field, the strength of the Andreev reflection ( and hence conductance of the junction ) is a function of the spin-polarization in the normal state.
48.
Herbertsmithite is the first mineral known to exhibit this unique state of magnetism : it is neither a ferromagnet with mostly aligned magnetic particles, nor is it an antiferromagnet with mostly opposed adjacent magnetic particles; rather its magnetic particles have constantly fluctuating scattered orientations.
49.
At the time, it was known experimentally that the liquid gas coexistence curve and the ferromagnet magnetization curve both exhibited a scaling relation of the form | T-T _ c | ^ { \ beta }, where \ beta was mysteriously the same for both systems.
50.
For example, a magnon in a ferromagnet can be considered in one of two perfectly equivalent ways : ( a ) as a mobile defect ( a misdirected spin ) in a perfect alignment of magnetic moments or ( b ) as a quantum of a collective spin wave that involves the precession of many spins.
