| 11. | These are the ferromagnetic, ferrimagnetic and antiferromagnetic materials.
|
| 12. | J < 0, i . e . the exchange coupling is antiferromagnetic.
|
| 13. | Another example is atomic magnetic moments with antiferromagnetic interactions.
|
| 14. | It can only be determined that the average correlation of neighbour spins is antiferromagnetic.
|
| 15. | The concept of antiferromagnetic coupling at short range.
|
| 16. | The magnetic susceptibility of an antiferromagnetic material typically shows a maximum at the N�el temperature.
|
| 17. | Ferromagnetic, paramagnetic, ferrimagnetic and antiferromagnetic structures are made up of intrinsic magnetic moments.
|
| 18. | Antiferromagnetic materials are weakly magnetic in the absence or presence of an applied magnetic field.
|
| 19. | It is an Ising model with long range frustrated ferro-as well as antiferromagnetic couplings.
|
| 20. | The susceptibility ( slope ) of the antiferromagnetic's magnetization curve is exaggerated for clarity.
