loops of perpendicularly magnetized or , or Ta , and spin valves. Inset: obtaining interlayer coupling field from minor loop shift.
(a) XRD patterns and XTEM images of spin valves with (b) Pd and (c) Ta seed layers.
Dependence of perpendicular interlayer coupling field, topological coupling, RKKY coupling, and GMR ratio on the Cu spacer thickness in the spin valves with (a) Pd and (b) Ta seed layers. The solid and dotted lines are guides to the eye and the open squares are values calculated using Eq. (1) and the solid circles are values calculated using topological coupling equation shown in the text.
Dependence of (a) perpendicular interlayer coupling field and GMR ratio and (b) deviation angle of the soft layer magnetization from the perpendicular direction and roughness on the Pd insertion layer thickness varied from in the spin valves.
