Abstract

Nuclear magnetic resonance (NMR) spectroscopy in the diamond anvil cell (DAC) has the potential to be a powerful tool for high pressure science as suggested by previous works. NMR in the DAC at high temperatures and pressures would be useful for exploring materials under Earth and planetary conditions. As a step toward realizing this goal, we fabricated a new type of diamond anvil cell from a nonmagnetic titanium alloy. The cell was designed to generate a multiplied force within a compact dimension for use in superconducting magnets. Using a handmade rf probe and NMR system, a spin echo train was successfully detected for liquid H₂O sample in the DAC at <1 GPa.
