| 1. | Magnetically driven ferroelectricity is also caused by inhomogeneous magnetoelectric interaction.
|
| 2. | This frustration leads to breaking symmetry which leads to ferroelectricity.
|
| 3. | Pyroelectricity is also a necessary consequence of ferroelectricity.
|
| 4. | These materials are said to exhibit ferroelectricity.
|
| 5. | Proper ferroelectricity now forms in domains.
|
| 6. | In 1974, R . B . Meyer predicted ferroelectricity in chiral smectic liquid crystals by pure symmetry conditions.
|
| 7. | From the soft mode theory of ferroelectricity, this occurs when a ferroelectric instability is stabilized by quantum fluctuations.
|
| 8. | At 760 K, the material undergoes a second order phase transition to a tetragonal perovskite structure which exhibits ferroelectricity.
|
| 9. | However, partially filled " d " shell on the B-site reduces the tendency of perovskites to display ferroelectricity.
|
| 10. | In addition, charge ordered ferroelectricity is suggested in Fe 3 O 4 and ( Pr, Ca ) MnO 3.
