In most well-studied ferromagnet / antiferromagnet bilayers, the Curie temperature of the ferromagnet is larger than the N�el temperature T N of the antiferromagnet.
12.
If an antiferromagnet is present in the sample, the coercivities measured in increasing and decreasing fields may be unequal as a result of the exchange bias effect.
13.
The moment of the magnetically ordered ferromagnet will apply an effective field to the antiferromagnet as it orders, breaking the symmetry and influencing the formation of domains.
14.
The amount of hysteresis shift H b is not correlated with the density " n " of uncompensated spins in the plane of the antiferromagnet that appears at the interface.

Easy-axis magnetization curves of a ) a soft ferromagnetic film; b ) an antiferromagnetic film and c ) an exchange-biased bilayer consisting of a ferromagnet and an antiferromagnet.
16.
Bose Einstein condensation of magnons was proven in an antiferromagnet at low temperatures by Nikuni " et al . " and in a ferrimagnet by Demokritov " et al . " at room temperature.
17.
The resistance change is a result of the antiferromagnet which acts to raise its magnetic coercivity and behaves as a " hard " layer, while the other is free ( unpinned ) and behaves as a " soft " layer.
18.
Just as all known conventional superconductors are strong phonon systems, all known high-" T " c superconductors are strong spin-density wave systems, within close vicinity of a magnetic transition to, for example, an antiferromagnet.
19.
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.
