Abstract

AbstractThe locally self-consistent multiple scattering method is applied to ab initio spin-polarized local density approximation calculations for ferromagnetic CuNi alloys. The samples used to model the alloys are constructed with experimentally measured short range order parameters. These large cell calculations are performed using the Intel Paragon XP/S massively parallel processing supercomputer. The neutron magnetic diffuse scattering cross sections are calculated and compared with experiment. The dependence of magnetic moment formation on the local environment is discussed.
