Figure 4
(a) Normalized magnetization at the remanent state as a function of the Mo spacer thickness. The positions of the layered samples with uniform thicknesses of the component layers at the dMo scale are also shown. LMOKE hysteresis loops for the sample exhibiting (b) antiparallel coupling (dMo = 0.9 nm) and (c) parallel alignment of magnetization (dMo = 1.8 nm). The arrows illustrate magnetization alignments in the component Co layers. |
