Abstract

Pulsed nuclear magnetic resonance measurements of the transverse frequency and magnetization of superfluid 3He in a 98.2% porous aerogel are observed at temperatures reduced significantly below the bulk 3He superfluid transition and are discussed in terms of an isotropic impurity scattering model. Magnetization measurements suggest an equal-spin pairing superfluid. For NMR tipping angles, 40°, the shifts drop abruptly to zero, unlike the known dependence of either the 3He-A or 3He-B superfluid phases.
