Pure {sup 3}He in highly porous aerogel forms an equal-spin pairing superfluid with transition temperatures suppressed from bulk values. We have measured the magnetic field dependence of the transition temperature from which it can be inferred that b

We have measured magnetic field distortion of the order parameter and the longitudinal resonance frequency of superfluid {sup 3}He-{ital B} using pulsed nuclear magnetic resonance. The experiments were guided by numerical solutions of Leggett{close_q

The transition to superfluidity of3He in high porosity (98.2%) acrogel has been observed by nuclear magnetic resonance techniques. The onset of the transition at all pressures above 13 bar is marked by a sharp increase in NMR frequency similar to tha

We have made accurate measurements of the phase velocity in liquid3He at 0.6 bar near Tc using a path length modulation technique. The frequency used in this measurement (113 MHz) is much higher than any of the collective mode frequencies and well ab

We have measured the velocity of first- and zero-sound in liquid3He at 12.6 MHz over the pressure range of 0.6 to 14.5 bar using a path length modulation technique that we have recently developed. From these measurements, the pressure dependent value

High-resolution nuclear magnetic resonance measurements of bulk superfluid [sup 3]He-[ital B] have been performed at temperatures above 0.5 mK and at pressures from 0.3 to 21.7 bars. We have found that the resonance frequency is shifted from the Larm
