Order-disorder and displacive components in the ferroelectric-paraelectric phase transition of potassium titanyl phosphate KTiOPO4.
In situ neutron powder diffraction analysis from 297 to 1358 K indicates the experimental evidence of the coexistence of order-disorder and displacive nature in the ferroelectric-paraelectric phase transition of potassium titanyl phosphate (KTiOPO(4), KTP).
