We present a manometer designed to measure pressures of 1–20 kbar in temperatures between 4–300 K in cylinder-piston type chambers, with an accuracy of ∼100 bar. The manometer is based on pressure-dependent zero-field 63Cu nuclear quadrupole resonance frequency corresponding to ‖±3/2〉↔‖±1/2〉 transition in Cu2O. The nuclear quadrupole resonance frequency νQ varies linearly with pressure and its temperature dependence is adequately explained by a model of lattice vibrational modes in O—Cu—O bonds. This manometer is particularly convenient for zero or high-field magnetic resonance experiments.
