Spin correlations on an Ising-like chain compound Sr4Mn2CoO9
The aim of this proposal is the caracterization of the spin correlations by polarized-neutron diffraction in Ising-like chain compound Sr(4-x)Ca(x)Mn2CoO9 for x=0 and x=2. The magnetic measurements and powder neutron diffraction performed on these compounds show a slow spin dynamics for both compounds and a long range ordering for the x=2 sample. The goal of this study is to track the evolution of the magnetic response as a function of the separation between the magnetic chains due to the substitution of Sr by Ca.
