The effect of doping on the magnetic damping parameter of Ni80Fe20 is measured for 21 transition metal dopants:Ti, V, Cr, Mn, Co, Cu, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Hf, Ta, W, Re, Os, Ir, Pt, and Au. For most of the dopants, the damping parameter increases linearly with dopant concentration.The strongest effects are observed for the bottom row transition metal dopants, with a maximum of 7.7 10-3 per atomic percent Osmium.
