This paper reports an NMR sample cell and probe design suitable for high sensitivity experimental studies, e.g. thin film studies of molecular hydrogen adsorbed on substrates such as hexagonal boron nitride. Easily machinable Kel-F (polychlorotrifluoroethylene or Fluorothene) is used in the NMR samp

β¦ Synopsis
A simple KeI-F coil former, preformed and heat shrunk onto metal posts, was used successfully for high-field NMR studies of solids and fluids at low temperatures (0.035 < T < 30 K) and for pressures of 0 < P < 4 MPa. The seals were vacuum tight to superfluid +He over the full pressure range.

Results of 27 Al-NMR measurements on the heavy-electron compound CeAl 3 , recorded in low magnetic fields (of the order of 1 kG), very low temperatures Γ°To1:5 KΓ, and at hydrostatic pressures up to 5.6 kbar are presented. We observe drastic changes of the NMR spectra and of the spin-lattice relaxati
A low-temperature, high-power NMR probe head design is described which eliminates the problem of electric arc discharge commonly experienced during radiofrequency pulse cycling in a helium environment. A polychlorotrifluoroethylene (Kel-F) coil former, fitted with a solenoid coil, is heat-shrunk ont
