AbstractThe behavior of AgReO4 under pressure has been studied in a diamond anvil cell. The equation of state determined by synchrotron radiation shows considerable change in compressibility with increasing pressure. X-ray and Raman scattering show a first-order phase transition from the scheelite to an as yet undetermined structure at 13 GPa. Changes in both the internal and external Raman active modes suggest a change in Re coordination. Optical transmission experiments demonstrate that the energy gap in the scheelitephase decreases at the rate of 75 meV/GPa. There is a small jump in the energy gap at 13 GPa, probably related to the structural transition. AgReO4 remains aninsulator to at least 47 GPa.

We investigated the structure transition and the electrocaloric effect in PbZr1-xTixO3 (PZT) with x=0.7, 0.8 and 0.9. The results show that 50 MV/m can make the structural transition be a continuous one. When x=0.7, 0.8 and 0.9 at the zero field, the first order structural transition occurs at T0=685, 687, and 698 K, respectively. Upon a strong electric field, the first order structural transition comes to the second one, which leads to lower the change of specific heat. The structural transition temperature is shifted at high temperature with increasing electric field. The maximum electrocaloric effect is present occurs at about 200 K above the corresponding Curie temperature. With increasing composition of Ti, the electrocaloric effect is enlarged, together with increasing structure transition temperatures.
