  A plastic turnbuckle diamond anvil cell (DAC) and nonmetallic gasket have
been developed for pulsed magnetic field studies to address issues of eddy
current heating and Lorentz forces in metal cells. The plastic cell evolved
from our 6.3 mm metal diameter turnbuckle DAC that was designed in 1993 to
rotate in the 9 mm sample space of Quantum Design's MPMS. Attempts to use this
metal DAC in pulsed magnetic fields caused the sample temperature to rise to
T>70 K, necessitating the construction of a nonconductive cell and gasket.
Pressures of 3 GPa have been produced in the plastic cell with 0.8 mm culets in
an optical study conducted at T = 4 K. Variations of the cell are now being
used for fermiology studies of metallic systems in pulsed magnetic fields that
have required the development of a rotator and a special He-3 cryostat which
are also discussed.
