摘要：
The Meissner effect in the normal metals induced by the proximity effect of Nb has been investigated in relation to the Kondo effect for Cu with dilute magnetic impurities: Mn and Fe, Co, Ni. The thickness rho of the Meissner region in Cu/Mn becomes nearly constant at low temperatures due to the magnetic scattering. The data provide a spin-flip scattering probability per 1ppm Mn of about 5 . 10(9)s(-1). A study was also made of the proximity effect for heavy-fermion materials: CeAl3 and CeCu6. No measurable Meissner effect was observed in these materials.
