Due to a special shape of Fermi surfaces in Pd and Pt metals, charge and magnetic impurity potentials induce the oscillatory shielding with large amplitude and extending to long distance along the [100] direction. As a result, Pd-M and Pt-M (M = Ti, V, Cr, Mn, Fe and Co) alloys show short range order of different types, but with the same symmetry. These are an atomic concentration wave for non-magnetic alloys (M = Ti, V, Cr), a spin-density-wave for spin-glass alloys (M = Cr, Mn) and a transverse spin modulation wave for ferromagnetic alloys (M = Fe, Co) .
