摘要：

We report measurements of spin-diffusion coefficients for 0.1 monolayerof3He adsorbed on thin4He filmsas a function of temperature and4He coverage. For4He coverages below a critical coverage Dc the 3He are immobile. The 3He quasiparticles in the film experience a mobility edge as the 4He coverage is increased beyond Dc. This is accompanied by a vanishing of local moments as evidenced by the disappearance of a Curie-like component of the magnetization for coverages D>Dc. A peak in the transverse relaxation T2 occurs near Dc. © 1995 The American Physical Society.
