A simple manometer for measuring pressures up to 15 kbar in clamp type cells is presented on the basis of the pressure dependence of zero-field NMR frequencies v in such ferromagnets as EuO and fcc Co. A narrow and intense 153Eu NMR in EuO is suitable for a NMR manometer with an accuracy of 0. 1 kbar at 4. 2 K. An intense, but rather broad 59Co NMR in fcc Co can be used in temperatures between 4. 2-300 K, where d v/dP is nearly independent of temperature. It is shown by using NMR manometers that the presssure in a clamp cell remains constant below 77 K.
