摘要：

We present a closed expression for the muon longitudinal field relaxation function which interpolates between the concentrated and the dilute spin glass function, originally introduced by Uemura et al. (Phys. Rev. B 31 (1985) 546.) A fast computational algorithm for a data-fitting routine is outlined and an application to an unconventional disordered magnetic system is pointed out.
