| The mixed crystals of NaNH4SO4·2H2O-NaNH4SeO4·2H2O were grown and their properties were investigated. Dielectric and differential thermal analysis studies allowed us to construct the phase diagram of the system with molar fraction, x, of NaNH4SeO4·2H2O as a parameter. Nonlinear dependence of Tc versus composition was found. |
