Keywords: phase transitions KTP isostructures.Ĭontains datablock General trends regarding the relationship between the room-temperature structures of KTP-like compounds and their T c values are discussed. Dielectric measurements show that the phase-transition temperature, T c, decreases with increasing germanium concentration, and a direct correlation between the room-temperature split of the rubidium cations and T c has been discovered. Additionally, rubidium split-cation positions have been found in these doped RTP crystals. The exchange of titanium for germanium results in a less distorted octahedral coordination around the two crystallographically independent titanium sites. In addition, a third structure, Rb 2(TiO) 2(PO 4) 2 (RTP), has been reinvestigated. ![]() ![]() MellanderĪbstract: Crystals of germanium-doped rubidium titanyl phosphate, Rb 2(Ti)(Ge 0.121Ti 0.879)O 2(PO 4) 2 (GeRTP#1) and Rb 2(Ge 0.125Ti 0.875)(Ge 0.225Ti 0.775)O 2(PO 4) 2 (GeRTP#2), have been structurally characterized from X-ray diffraction data at room temperature. ![]() B 59, 588-595 Phase transitions in KTP isostructures: correlation between structure and T c in germanium-doped RbTiOPO 4 S. ![]()
