2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/18231We 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 $(00l)$ direction, and the analyses of such scattering leads to a conclusion that the low temperature spin structure is a canted antiferromagnetic ordering.4 pages, 3 figures Email: mkubota@post.kek.jpStrongly Correlated Electronstext
