摘要：

The complex dielectric constant of Rb1-x(NH4)(x)H2AsO4 mixed crystals is measured for the concentrations x = 0.17 and 0.19. It reveals a proton-glass state preceded by the ferroelectric phase transition as the temperature decreases. A complementary laser optical study suggests that the ferroelectric orthorhombic symmetry remains down to the low temperature where the glass state is established. Hence, the proton-glass state coexists with the long-range ferroelectric order of orthorhombic symmetry, and the glass freezing may occur quite independently of the ferroelectric order.
