Muon-spin relaxation in systems of dilute dipolar impurities: Numerical treatment of fluctuations

摘要: Muon-spin depolarization lineshapes for systems with random dilute distributions of magnetic-dipolar impurities are examined using numerical, methods. Analyses models presented which analogous to μSR experiments on spin-glass materials carried out in zero external magnetic field. The width the Lorentzian distribution local field is about a factor two larger than case where there an A Monte-Carlo method used treat several model cases simulate influence impurity-dipole relaxation spectra. novel results considers muon diffusion also presented.
