Query: Neutron Scattering Studies on Magnetic Structure of the Double-Layered
  Manganite La_{2-2x}Sr_{1+2x}Mn_2O_7 ($0.30 \leq x \leq 0.50$)   Systematic powder diffraction studies have been carried out to establish the
magnetic phase diagram of La_{2-2x}Sr_{1+2x}Mn_2O_7 (LSMO327) in a wide hall
concentration range ($0.30 \leq x \leq 0.50$), using the HERMES diffractometer.
LSMO327 exhibits a planar ferromagnetic structure for $0.32\leq x\leq 0.38$ at
low temperatures. A finite canting angle between planar magnetic moments on
neighboring planes starts appearing around $x\sim 0.40$ and reaches
180$^{\circ}$ (A-type antiferromagnet) at x=0.48. At x=0.30, on the other hand,
the magnetic moments are aligned parallel to the c-axis.
