  Recent neutron scattering measurements on the La2-xSrxCuO4 system have
revealed a drastic change of the incommensurate static spin correlations from
diagonal in the insulating region to parallel in the superconducting region. We
report the doping dependence of the ordered magnetic moment for the hole
concentration region 0.03 <= x <= 0.12, focusing on the relationship between
the static magnetism and the superconductivity. The elastic magnetic
crosssection decreases monotonically with increasing x for 0.03 <= x <= 0.07.
We find that the ordered magnetic moment \mu varies from ~0.18 (x=0.03) to
\~0.06 \mu_B/Cu (x=0.07). No significant anomaly is observed at the
insulator-superconductor boundary (x ~ 0.055). The elastic magnetic
crosssection is enhanced in the vicinity of x=0.12 whose resolution limited
width peaks are observed in neutron scattering measurements and where the
apparent magntic and superconducting transitions coincide.
