Abstract
We have examined magnetic ordering of the two-dimensional (2D) bilayer manganite La1.1Sr1.9Mn2O7 with neutron diffraction technique. Due to the two-dimensionality, there appears intense 2D ridge scattering along the tetragonal (00l) direction, and the analyses of such scattering leads to a conclusion that the low temperature spin structure is a canted antiferromagnetic ordering.
