| 21. | In the antiferromagnetic case, a divergence is observed in the " staggered susceptibility ".
|
| 22. | Various microscopic ( exchange ) interactions between the magnetic moments or spins may lead to antiferromagnetic structures.
|
| 23. | Heat capacity measurements reveal an event at 78.3 K corresponding to ordering of antiferromagnetic state.
|
| 24. | This makes possible magnetic imaging down to the atomic scale, for example, in antiferromagnetic system.
|
| 25. | If they have the same magnitude, the crystal is antiferromagnetic and possesses no net magnetic moment.
|
| 26. | Erbium is ferromagnetic below 19 K, antiferromagnetic between 19 and 80 K and paramagnetic above 80 K.
|
| 27. | Type-I multiferroics which have been known for a long time are often good ferroelectrics and antiferromagnetic.
|
| 28. | Their gap opens thanks to an unusual antiferromagnetic coupling between the magnetic moments at opposite edge carbon atoms.
|
| 29. | Almandine is antiferromagnetic with the N�el temperature of 7.5 K . It contains two equivalent magnetic sublattices.
|
| 30. | High quality single crystals have been important for studying the ferroelectric, antiferromagnetic and magnetoelectric properties of bismuth ferrite.
