Searching for the missing phase of SrTiO3; commissioning a new cryogenic pressure cell for WISH.

Abstract: Generating pressure above 1GPa for neutron diffraction typically requires the use of a Paris-Edinburgh press. Whilst the presses operate very reliably at ambient temperature, their design is not well suited for low temperature studies below 60 Kelvin. We have developed, in collaboration with the ISIS facility, a new compact pressure cell for use at temperatures less than 1 Kelvin, operable over a similar pressure range. The cell can be cooled quickly using conventional CCRs and cryostats, and has been designed to avoid the need to warm the cell to room temperature to change the pressure. Here we hope to complete the commissioning of this pressure cell, incorporating several new design improvements. As a trial experiment, we have chosen to study SrTiO3; we hope to determine the existence of a new phase under pressure at base temperatures, which is otherwise suppressed by quantum effects.
