Spin reorientation in Na-doped BaFe${}_2$As${}_2$ studied by neutron diffraction

F. Wasser, A. Schneidewind, Y. Sidis +4

We have studied the magnetic ordering in Na doped BaFe${}_2$As${}_2$ by unpolarized and polarized neutron diffraction using single crystals. Unlike previously studied FeAs-based compou…
