Abstract

Spin polarization of tunnelling electrons from Ni1-xPtx and Ni1-xPdx was measured in a lower concentration range of Pt and Pd. The observed spin polarization P was not proportional to the bulk magnetization. The values of P attain maximum at about x ≅ 0.03 for Ni1-xPtx and x ≅ 0.01 ∼ 0.05 for Ni1-xPdx alloys, while the bulk magnetization decreases monotonically with increased Pt or Pd concentration. Present data are different from the ones of Meservey's results on the 3d transition metal alloys.
