We consider the contribution of a two-loop Barr-Zee type diagram to (g−2)μ in the minimal supersymmetric standard model (MSSM). At relatively large tanβ, we show that the contribution of light third generation scalar fermions and neutral CP-even Higgs, h0(H0), can easily explain the very recent BNL experimental data. In our analysis (g−2)μ prefers negative Af and positive μ. It is more sensitive to the chirality flipping h0(H0)\wtfR∗\wtfL rather than chirality conserving couplings.
