Abstract
A crystal of Cs-1-x(NH4)(x)HSO4 (x=0.1) has been prepared by slow evap oration at room temperature. This crystal is of about(1x1x0.5) mm(3) a nd is monoclinic at room temperature. DSC, dielectric, optical and inf rared measurements allow us to detect a second-order or slightly first -order phase transition at 346 K and a first-order phase transition: s uperionic protonic phase transition (SPT) at 410 K.
