摘要:

我们报告的实验结果与超流3 He限制在气凝胶与平行股,导致各向异性散射的3 He准粒子。我们通过覆盖不同数量的原子4 He层的股散射不同的边界条件,并观察到超流相图和超流相的性质强烈依赖于覆盖范围。我们认为,这些现象的主要原因是一个磁通道的散射变得重要,在低覆盖率。我们的结果表明,磁通道在其他三重态费米系统中也可能是重要的。

英文摘要:

We report results of experiments with superfluid 3He confined in aerogels with parallel strands which lead to anisotropic scattering of 3He quasiparticles. We vary boundary conditions for the scattering by covering the strands by different numbers of atomic 4He layers and observe that the superfluid phase diagram and the nature of superfluid phases strongly depend on the coverage. We assume that the main reason of these phenomena is a magnetic channel of the scattering which becomes important at low coverages. Our results show that the magnetic channel also may be important in other Fermi systems with the triplet pairing.
