摘要：

The effects of random strain fields on the tetragonal-orthorhombic phase transition in mixed Dy(As(x)V(1-x))O4 crystals have been studied by neutron scattering. In the ordered phase the diffraction peaks, which are characteristic of {110} twinning, show transverse or mosaic-type broadening, which disappears when the sample is forced into a single domain. The data are consistent with a model based on roughening of {110} domain walls, which predicts a h 2/3 dependence of broadening on random fields.
