Abstract

We calculate the dependence of the nuclear magnetic moments on the quark masses, including the spin-spin interaction effects, and obtain limits on the variation of the fine structure constant \ensuremathα and (m_q/\ensuremathΛ_QCD) using recent atomic clock experiments examining hyperfine transitions in H, Rb, Cs, Yb⁺, and Hg⁺ and the optical transition in H, Hg⁺, and Yb⁺.
