Aluminum Alloy Microstructure Properties

3 1 ~ NMR data allow to demonstrate that Coulomb interactions induce spin localisation in slightly metallic Si:P.The observed nuclei are associated with delocalised electrons (weak xion enhanced Pauli susceptibility, nuclear Korringa relaxation).The fraction of Iocalised spins, which wipe out 3 1 ~ nuclei from the observed signal, increases through the transition.
