Abstract
The diamagnetism of platinum metals (N: Rh, Pt, Pd), which is induced by the proximity effect of a superconductor (S: Nb), has been investigated for N−S double layers. Notwithstanding the strong spin fluctuation in platinum metals, the screening distance ρ in N increases with a decrease in temperature and reaches a value that is expected in comparison with ρ in Cu. When magnetic impurities are included in N, the proximity effect is drastically suppressed and the paramagnetism due to a giant moment is observed.
