Abstract
High-pressure Raman studies on potassium-rare earth double molybdates, KDy(MoO4)2 and KY(MoO4)2, up to 35 GPa are reported. The Raman data indicate the occurrence of a reversible pressure-induced phase transition near 3 GPa, from the orthorhombic Pbcn phase. High-pressure x-ray diffraction measurements suggest that the new phase is also orthorhombic and has a smaller volume. The phase transition is structurally similar to that observed in KTb(MoO4)2 near 3 GPa and seems to be characteristic of the layer-type orthorhombic, potassium-heavy rare earth dimolybdates. Changes in optical transmission observed in all three dimolybdates are compared and discussed.
