N2 - We report the first observation of a Γ8 (quartet) resonance in a metal (Au:Dy). The field for resonance determines the relative magnitude and sign of the crystal-field parameters, B4B6=1300±30, to be compared with that found for Ag:Dy alloys, ≤340. The linewidth yields an exchange-coupling parameter Jfs=0.14±0.05 eV, slightly larger than for Au:Gd and Au:Er alloys, and slightly smaller than for silver-based alloys.
