Abstract
The K3Lu1-xYbx(PO4)(2), Rb3Dy(PO4)(2) et K2RbHo-(PO4)(2) compounds exhibit a phase transition (rhombohedral --> monoclinic) produced by a pressure eff ect. For these compounds, we have determined the pressure value inducing th is transition by the et amination of the evolution of infrared spectra reco rded using KBr pellets obtained at different pressure. The region of the co existence of both rhombohedral and monoclinic phases has also been determin ed.
