We present zero-field muon-spin depolarization measurements in nickel and silver performed using low-energy muon-spin relaxation technique. Ni or Ag are usually used in this depth-resolved technique as a backing material to enable background subtraction when studying small crystals or materials with weak magnetism. The depolarization rate of the asymmetry in silver and that of the slow relaxing part of the asymmetry in nickel are small (≤ 0.05 μs^–1), and weakly temperature and energy-dependent.
