โœฆ Synopsis

The low-field NMR spectra of 8He boundary layers on graphite show collective modes for T < 1mK One of these modes has a nonzero frequency and amplitude at zero field.

We show the frequency and amplitude of these modes as a function of the applied magnetic field and the total amplitude as a function of temperature for a number of fields.

Continuous wave NMR was used to study pure 3He films at coverages from below 2nd layer completion to above the ferromagnetic peak coverage at -2.5 layers. The films were adsorbed on Grafoil and were cooled to temperatures as low as 0.075 mK. The first layer magnetization followed Curie law very well

Continuous-wave (cw) nuclear magnetic resonance measurements have been made at 5.SMHz of 3He adsorbed on Grafoil and on argon (monolayer)-coated Grafoil at coverages x <-0.40 (x = 1 corresponds to one monolayer), in the temperature range 0.35-4.21 K. To determine the fractional coverages, the adsorp

Measurements have been made of the adsorption isotherms of 3He and of para-hydrogen (p-He), on bare Grafoil, the former in the temperature range 0.88-1.23 K, and the latter in the temperature range 10.0-20.0K. For p-He the quantity of material adsorbed plotted against (p/pO) T yields a single temper
