Angular dependencies of the rotated reflectivity (left part) and asymmetry ratio (right part), calculated by the exact theory (thin solid red lines) and by (52), (51) and (53) (thick dashed green lines) for different cases of the magnetic ordering between Gd layers: for ferromagnetic interlayer coupling [Gd(4 nm)/Ti(3 nm)]8, for antiferromagnetic interlayer coupling [Gd↑(4 nm)/Ti(3 nm)/Gd↓(4 nm)/Ti(3 nm)]4 and for helical ordering with magnetic period 28 nm. |
