正常和超流3 He的低温磁化率限制在聚酯薄膜箔间隔4.0 μ m，显示了一个大的和场依赖的增强体费米液体的大小。当掺杂0.5%4He时，超极化率消失.过量的原因尚不清楚。作者还研究了聚酯薄膜衬底的质子共振，并获得了足够大的自旋极化，以允许直接观察双自旋翻转RF吸收。
The low-temperature magnetic susceptibility of normal and superfluid 3 He confined between mylar foils spaced 4.0 mu m apart shows a large and field-dependent enhancement over the bulk Fermi liquid magnitude. The excess susceptibility disappears when the liquid is doped with 0.5% 4 He. The reason for the excess is unknown. The authors also studied the proton resonance of the mylar substrate and obtained spin polarizations large enough to permit the direct observation of double spin-flip RF absorption.
