20nm-Fe/dZr-Zr/20nm-Fe and 20nm-Fe/dTi-Ti/20nm-Fe trilayers with wedged Zr and Ti sublayers were prepared at room temperature using UHV (5 × 10-10 mbar) RF/DC magnetron sputtering. Results showed that the Fe sublayers are ferromagnetically coupled up to Zr and Ti spacer thickness of about 1.5 and 2 nm, respectively. Furthermore, a weak antiferromagnetic (ferromagnetic) coupling of the Fe sublayers was observed for a Zr (Ti) thickness range between 1.5 and 3 nm (2 and 3.4 nm). The Fe sublayers are very weakly exchange coupled or decoupled for dZr > 3 nm and dTi > 3.4 nm. The small decoupling Ti and Zr thickness could be explained by spontaneous formation of a quasi-amorphous structure of the paramagnetic spacer during the deposition process.
