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

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 report pulsed nuclear magnetic resonance (NMR) measurements of the transverse frequency and magnetization of3 He confined in aerogel with 98.2% open volume porosity. A homogeneous superfluid phase is observed at pressures, P > 12 bar, accompanied

Pulsed nuclear magnetic resonance measurements of the transverse frequency and magnetization of superfluid ${}^{3}\mathrm{He}$ in a 98.2% porous aerogel are observed at temperatures reduced significantly below the bulk ${}^{3}\mathrm{He}$ superfluid

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

We present pulsed NMR measurements of the low temperature (≈0.003 K) magnetic susceptibility of normal liquid 3 He as a function of pressure. Our results agree well with the extrapolation from 0.035 K of the data of Ramm et al. We calculate new val
