In addition to variation of temperature and application of external magnetic fields the electronic properties of many materials may be influenced by application of pressure. The highest pressures can be achieved in diamond anvil cells (DAC) but limited sample size and anvil cell geometry hampered their application in nuclear magnetic resonance (NMR) experiments due to a weak signal-to-noise. Recently we succeeded in improving the sensitivity of NMR measurements in DACs significantly by placing the radio-frequency coil containing the sample in the high-pressure region. Here we report on first high-sensitivity measurements at pressures up to 70 kbar.
