Abstract
The magnetic structure and its correlation with the Jahn-Teller (JT) distor tion in lightly doped La1-xSrxMnO3 (0.11 less than or equal to x less than or equal to 0.185) have been studied as a function of temperature from 10-3 00 K using neutron powder diffraction. A correlation between the ferromagne tic spin orientation and the coherent JT distortion was observed, indicatin g a coupling between the structural acid the magnetic properties. The arran gement of the spins varies from ferromagnetic ordered mainly along the b ax is (x = 0.11) to ferromagnetic almost along the c axis (x=0.185) in the Pbn m symmetry.
