Phase diagrams of incommensurate ferroelectric NH₄HSeO₄: phenomenological treatment
The phenomenological analysis of the pressure-temperature (P −T ) phase diagram of NH₄HSeO₄ crystals is presented. It is shown that the disagreement between the experimental results and the theory may be removed assuming that the coefficient of the Landau free-energy expansion κ at the gradient te...
