Monte Carlo Study Of A Model For The Mixed Crystal Rb_1-x(NH₄)_xH₂P_O4

A microscopic model for the mixed crystal Rb1_x(NH4)xH2PO4is introduced which takes into account the acid protons as well as the NH4groups. Using Monte Carlo simulation, the topology of the experimentally determined phase diagram is reproduced rather well, including the onset of freezing into a glasslike state. © 1986, Taylor & Francis Group, LLC.
