摘要:
Spin‐echo NMR studies on amorphous Co‐P alloys are made at 4.2K in zero and applied magnetic fields. A broad distribution of hyperfine fields is observed with maxima shifting to higher frequencies with decreasing P content. The NMR spectra arise predominantly from CO59nuclei. Preliminary results on relaxation and annealing effects are presented.

摘要:
The Brooks‐Yu formalism for calculating the electronic properties of crystals at finite temperature has been generalized to a multiple scattering series based ont‐matrices rather than pseudo‐potentials. The resulting expression leads both to shifts in the electronic eigenvalues and damping of the eigenstates as a function of temperature. As a model of structurally disordered metals, this viewpoint overestimates the local atomic correlations in contrast to theories which include only two particle correlation functions. Calculations for Al and Cu at their melting temperatures are discussed.
