Abstract
Zero and transverse-field µSR has been measured on fcc Fe66Ni34 Invar alloy. The hyperfine coupling is obtained Ahf ~ -2.4 kG/µB. The muon spin relaxation rate above Tc follows 1 / Tµ = 2.2 / (T - Tc) (µs)-1. These facts seem microscopically consistent with the deviation from the Slater-Pauling curve and the reduction of the local moment.
