The magnetic moments of the first 2+ excited states of even Ni isotopes have been measured using the large dynamic magnetic fields acting on fast ions traversing thin magnetized iron foils. The results obtained are g(Ni58,21+)=-0.06±0.13, g(Ni60,21+)=0.09±0.12, g(Ni62,21+)=+0.33±0.12, and g(Ni64,21+)=+0.45±0.12. These results agree with shell-model calculations presented here and contradict previous calculations.
