Achieving High Static Pressures in Pulsed Magnetic Fields

Extreme pressure allows for creation of materials with desirable properties and behaviors that do not normally exist under ambient conditions, such as high-temperature superconductivity, high-energy density phases, and electronic topological phase transitions. The combination of extreme condition pathways, such as the application of pressure in conjunction with the ability to apply high magnetic fields allows for both a deeper understanding of the underlying fundamental behaviors of a given system, as well as the ability to access properties not measurable without the use of both, such as magnetotransport measurements of high superconducting crtical transition temperature materials. However, the constraints imposed by both of these techniques makes these measurements considerably more difficult when combined.

In this contributed talk, I will discuss some of the difficulties imposed by applying large pulsed magnetic fields in conjunction with high, static pressures applied using the diamond anvil cell (DAC), as well as progress made in cell design in pulsed fields. I will also discuss our recent success measuring a cerium hydride sample synthesized under high pressures and measured in pulsed fields, in which both the upper critical field limit, H_C2, and Hall measurements were able to be measured at 1.2 MBar and fields up to 59 T.
