Low temperature magnetization measurements in magnetic fields up to 55 kOe are reported for a series of PdRhNi alloys containing 1 to 7 at.% Rh and up to 1 at.% Ni. These data indicate a critical Ni concentration for ferromagnetism close to 2 at.%. Comparison of the field and concentration dependence of the susceptibility to the magnetoresistance data of Purwins et al. reveals that the coefficient of the T2 local spin fluctuation resistivity scales directly with the nickel susceptibility. Experimentally, the scaling parameter varies only slightly with Rh concentration, a result which extends to the binary PdNi alloys.

Fluctuation Effects

The renormalized local-spin–fluctuation theory of Paton and Zuckermann is extended in a temperature-dependent calculation. It is found that the temperature dependence of the renormalization parameters produce significant quantitative effect in the linear-T region of the effective density of d states.

A model with interlayer pairing is proposed to explain the sinusoidal modulation of the resonant neutron scattering in high temperature superconductors. It is found that the interlayer pairing has s-wave symmetry in the CuO 2 plane and has comparable magnitude with the d-wave intralayer pairing. It is also found that the interlayer pairing mainly affects momentum close to the hot spots on the Fermi surface while its effect on the gap nodes is negligible. It is pointed out that these characteristics of the interlayer pairing can be understood in a model in which the superconducting pairing originates from the exchange of the antiferromagnetic spin fluctuation.
