摘要：

Polarized neutron diffraction on La2-xSrxNiO4 (x=0.275 and 1/3) reveals that the spins in the ordered phases are canted in the NiO2 plane away from the charge and spin stripe direction. The deviation angle is larger for x=1/3 than for x=0.275. Furthermore, for the optimal x=1/3 stoichiometry, an enhancement of the charge contribution and a larger canting of the spins occur below 50 K, which indicates a further lock in of the doped holes.
