Abstract
The nuclear-magnetic-resonance (NMR) and susceptibility behavior of the intermetallic compound Au differs anomalously from the isoelectric and isostructural compounds Au and Au. In an effort to test and extend the explanation offered by Jaccarino et al. and by Switendick and Narath, spin-lattice relaxation times and Knight shifts have been measured as a function of temperature and composition for the Au-Au, Au-Au, and Au-Au pseudobinary alloy systems. At high temperature, the solute (Al, In, Ga) resonance properties are dominated by the host. Satellite resonances are observed with temperature dependences differing from the main resonance. The results are partially explainable on the basis of an average-band model and partially on a local atom model. The role of the Au bands is discussed. Metallurgical results on alloying are obtained using the NMR data.
