abstract

We calculate the strange magnetic moment of the nucleon on a quenched
$16^3 \times 24$ lattice at $\beta = 6.0$ and with Wilson fermions at
$\kappa$ = 0.148, 0.152, and 0.154. The strange quark contribution
arising out of the
disconnected insertion is estimated stochastically by employing the
$Z_2$ noise method. Using an unbiased subtraction along with the help of
charge conjugation and hermiticity we reduce the error significantly.
Our result is $G_{M}^{s} = -0.28\pm0.10$.
