Dynamics of KH2PO4 type ferroelectric phase transitions
2014 We include the configuration energy in Kobayashi’s theory for KDP-type ferroelectric crystals. The theory is then shown to be coherent from the thermodynamical point of view, as the order parameter and the frequency of the associated soft mode vanish at the same temperature. The results show that it is possible to have another kind of mixed ferroelectric, where the displacive phenomenon tr...
متن کاملPressure-induced phase transition in PbSc0.5Ta0.5O3 as a model Pb-based perovksite-type relaxor ferroelectric.
We report pressure-induced structural changes in PbSc(0.5)Ta(0.5)O3 studied by single-crystal x-ray diffraction and Raman scattering. The appearance of a soft mode, a change in the volume compressibility, broadening of the diffraction peaks, and suppression of the x-ray diffuse scattering show that a phase transition occurs near pc approximately 1.9 GPa. The critical pressure is associated with...
متن کاملSpecific heat of the Skyrmion lattice phase and field-induced tricritical point in MnSi.
We report high-precision measurements of the temperature and magnetic field dependence of the specific heat, C(T,H), across the magnetic phase diagram of MnSi. Clear anomalies establish the Skyrmion lattice unambiguously as a thermodynamic phase. The evolution of the specific heat anomalies, the field dependence of the entropy released at the phase transitions, and the temperature versus field ...

15 صفحه اولCalculated pressure-induced phase transition in MgF2
Relatively little attention has been paid to pressureinduced phase transitions in the Group II halides in contrast to the volume of work on the Bl-B2 transition in the alkali halides and alkaline-earth oxides. However, recently the rutile to fluorite transition in MgFz has been the subject of a paper by Nga and Ong,’ in which they studied this transition by molecular dynamics simulation based o...
