High‐pressure–low‐temperature apparatus for NMR study of phase transitions

An apparatus has been developed for nuclear‐magnetic‐resonance (NMR) measurement of relaxation times in solids at hydrostatic pressures to 7 kbar and temperatures down to 77 K. Sample temperature can be controlled accurately with ±2 mK stability allowing measurement of dynamic phenomena very near ph...

Beschreibung
Zusammenfassung:	An apparatus has been developed for nuclear‐magnetic‐resonance (NMR) measurement of relaxation times in solids at hydrostatic pressures to 7 kbar and temperatures down to 77 K. Sample temperature can be controlled accurately with ±2 mK stability allowing measurement of dynamic phenomena very near phase transitions. The high‐pressure vessel is equipped with additional electrical feedthroughs so that dielectric measurements can be carried out concurrently, providing additional information on ferroelectric phase transitions.
