Using a vector meson dominance model fitted to BaBar data, the e+e- to K+K- pi0 pi0 cross section yields a central value of 4.5 and upper bound of 6.3 for the K* magnetic dipole moment in units of e/2m_K*.

Effect of $K^*$ meson magnetic dipole moment on the $e^+e^- \to K^+ K^-\pi^0 \pi^0 $ cross section
Using a vector meson dominance model fitted to BaBar data, the e+e- to K+K- pi0 pi0 cross section yields a central value of 4.5 and upper bound of 6.3 for the K* magnetic dipole moment in units of e/2m_K*.
