Separation of Micron-Scale Particles by Size Using Helium II
Here we report on a new technique we are develo** to classify micron scale particles, i.e., separate them by size, using superfluid 4He (He II). The technique is based on the unique property of He II, that is i...

Nuclear Magnetism of Normal 3He and 3He-4He Mixtures in Aerogel
We report NMR experiments at 8 T on 3 He and 3 He- 4 He mixtures filling the pores of 95% porous aerogel, for temperatures T ≥ 6 mK. Magnetization measurements of pure 3 He reveal a localized layer approximately...

NMR experiments on pure3He and3He-4He mixtures in silica aerogel
We have carried out a series of NMR experiments on3He systems filling the pores of silica aerogel with 95% porosity. The systems studied included3He-4He mixtures with a wide range of3He concentrations x3 as well ...

Transport experiments on dilute, spin-polarized Fermi fluids
A series of experiments has been carried out on very dilute3He-4He mixtures and on pure3He liquid at very high field/temperature ratios (H≤8 T, T≥4.3mK). In this regime these systems display a strong Leggett-Rice...
