Homogeneous Equal-Spin Pairing Superfluid State of3Hein Aerogel

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 transition and are discussed in terms of an isotropic impurity scattering model. Magnetization measurements suggest an equal-spin pairing superfluid. For NMR tipping angles, $\phi 40°$, the shifts drop abruptly to zero, unlike the known dependence of either the ${}^3\mathrm{He}-A$ or ${}^3\mathrm{He}-B$ superfluid phases.
