The magnetic structure and its correlation with the Jahn-Teller (JT) distortion in lightly doped La{sub 1{minus}x}Sr{sub x}MnO{sub 3} (0.11{le}x{le}0.185) have been studied as a function of temperature from 10{endash}300 K using neutron powder diffraction. A correlation between the ferromagnetic spin orientation and the coherent JT distortion was observed, indicating a coupling between the structural and the magnetic properties. The arrangement of the spins varies from ferromagnetic ordered mainly along the {ital b} axis (x=0.11) to ferromagnetic almost along the {ital c} axis (x=0.185) in the {ital Pbnm} symmetry. {copyright} {ital 1999} {ital The American Physical Society}
