Query: Composite Pressure Cell for Pulsed Magnets   Extreme pressures and high magnetic fields can affect materials in profound
and fascinating ways. However, large pressures and fields are often mutually
incompatible; the rapidly changing fields provided by pulsed magnets induce
eddy currents in the metallic components used in conventional pressure cells,
causing serious heating, forces and vibration. Here we report a
diamond-anvil-cell made mainly out of insulating composites that minimizes
inductive heating while retaining sufficient strength to apply pressures of up
to 9 GPa. Any residual metallic components are made of low-conductivity metals
and patterned to reduce eddy currents. The simple design enables rapid sample
or pressure changes, desired by pulsed-magnetic-field-facility users. The
pressure cell has been used in pulsed magnetic fields of up to 65 T with no
noticeable heating at cryogenic temperatures. Several measurement techniques
are possible inside the cell at temperatures as low as 500 mK.
