Abstract
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).
摘要
从297K到1358K的原位中子粉末衍射分析表明，有实验证据证明钛酸氧钾（KTiOPO₄，KTP）在铁电-顺电相变过程中存在有序-无序和位移性本质的共存。
