| 31. | Therefore, weak acid annealing suppresses the antiferromagnetic correlation by deintercalating the excess Fe and, hence superconductivity is achieved.
|
| 32. | The state with spins opposed has lower energy, so the interaction can be classed as antiferromagnetic in this case.
|
| 33. | There are also examples of disordered materials ( such as iron phosphate glasses ) that become antiferromagnetic below their N�el temperature.
|
| 34. | For the triangular lattice, which is not bi-partite, the ferromagnetic and antiferromagnetic Ising model behave notably differently.
|
| 35. | Below 200 K there is a minor change to the structure which changes the symmetry to rhombohedral and samples become antiferromagnetic.
|
| 36. | Earlier reports indicated that excess Fe is the cause of the bicollinear antiferromagnetic order and is not in favor of superconductivity.
|
| 37. | The transition from antiferromagnetic to paramagnetic ( or vice versa ) occurs at the N�el temperature which is analogous to Curie temperature.
|
| 38. | Exchange anisotropy has long been poorly understood due to the difficulty of studying the dynamics of domain walls in thin antiferromagnetic films.
|
| 39. | Accordingly, the rest of groups of crystal symmetry where QMR can be observed constitutes 27 antiferromagnetic and 31 pyromagnetic crystal classes.
|
| 40. | Below 118 K MnO is antiferromagnetic . to have its magnetic structure determined by neutron diffraction, the report appearing in 1951.
