Abstract

We have examined magnetic ordering of the two-dimensional (2D) bilayer manganite La $_{1.1}$ Sr $_{1.9}$ Mn $_{2}$ O $_{7}$ with neutron diffraction technique. Due to the two-dimensionality, there appears intense 2D ridge scattering along the tetragonal $(00 l)$ direction, and the analyses of such scattering leads to a conclusion that the low temperature spin structure is a canted antiferromagnetic ordering.
