      abstract     = {A neutron powder diffraction (NPD) study on the crystal and
                      magnetic structure of a crushed La1-xSrxMnO3 (x approximate
                      to 1/8) single crystal has been performed. The sample
                      belongs to orthorhombic (Pnma, O) above the Jahn-Teller (JT)
                      transition temperature (T-JT) and monoclinic (P12(1)/c1, M')
                      in the JT regime. We have also refined the NPD data below
                      the charge/orbital ordering (CO/OO) temperature (T-CO/OO)
                      with a monoclinic (P12(1)/c1, M'') model because the
                      experimental resolution was insufficient to clearly identify
                      a triclinic (P (1) over bar) structure. The refined lattice
                      parameters show an obvious breathing-mode distortion between
                      T-CO/OO and T-JT, accompanied by a large deviation of the
                      monoclinic angle beta from 90 degrees, signifying a very
                      strong cooperative JT distortion. A ferromagnetic (FM)
                      moment of 3.43(5) mu(B)/Mn besides an A-type
                      antiferromagnetic (A-AFM) moment of 0.54(2) mu(B)/Mn is
                      directed mainly along the b axis in P12(1)/c1 symmetry at 5
                      K. With increasing temperature, the A-AFM domains transform
                      into FM ones above similar to 100 K and the FM spin
                      orientation turns from the b to the c axis in
                      crystallographic b-c plane below T-c = 187(1) K. The
                      magnetization measurements show typical anomalies around
                      T-CO/OO and T-JT. The measured saturation moment of 3.9(1)
                      mu(B)/Mn at 70 kOe and 5 K is well consistent with the sum
                      3.97(5) mu(B)/Mn of the refined FM and A-AFM moments at 5 K,
                      implying the A-AFM spins are aligned in field direction at
                      70 kOe. The applied magnetic field can affect the
                      paramagnetic insulating (PMI) state in the range of magnetic
                      polarons. Based on the size of JT distortion and the
                      bond-valence sums (BVS's), the CO/OO phenomenon is being
                      discussed.},
