| dc.description | In further neutron scattering experiments on the (orthorhombic) ferroelectric phase of DCsDA and CsDA, a study has been made of the scattering arising at wavevectors along the a* direction at positions away from Bragg reflections. It is shown that this most probably arises from Bragg scattering in which two different ferroelectric domains are involved. Below T<sub>c</sub> each Bragg reflection can split into four separate spots corresponding to the different domain types. Surprisingly in DCsDA a central Bragg spot from the (tetragonal) paraelectric phase persists with decreasing intensity over a 60K temperature range. This effect has been observed with both neutron and X-ray scattering techniques and is independent of crystal size. |
