| Abstract: | Abstract High-pressure neutron-diffraction studies have been carried out on KH2PO4, KD2PO4, H2C4O4 and PbHPO4, using single-crystal samples. The results show that changes in the H-ordering temperature, TC, with pressure (or deuteration) in these systems can be largely attributed to the variation of the H-site separation, δ, with pressure (or deuteration). |
