TbFeco film with W underlayer and overlayer for perpendicular magnetic recording

“…6). The second one is a possibility of spin polarization of non-magnetic W as the saturation magnetization of Co/Pd [7] and Fe/Ag [8] multilayer have shown to exceed those of pure Co and Fe films, respectively, because of spin polarization of non-magnetic layers. In this case, spin polarization of W may not be the cause for the increase in M s , as the authors have not found any increase in M s in the W/Fe multilayer.…”

Dependency of anti-ferro-magnetic coupling strength on Ru spacer thickness of [Co/Pd]n-synthetic-anti-ferro-magnetic layer in perpendicular magnetic-tunnel-junctions fabricated on 12-inch TiN electrode wafer

“…The indirect anti-ferro-magnetic coupling across Ru spacer-layer has been attributed to Ruderman-KittelKasuya-Yosida (RKKY) interactions mainly mediated by 3d electrons, where the magnetization of two Co layers adjacent to the Ru spacer layer is oriented anti-parallel or parallel. [19][20][21] The clear oscillatory decay behavior was observed with a period of 1.2 nm and the anti-ferromagnetic peak at the t Ru of 0.6 nm, respectively. Both H ex and J ex increased with t Ru up to 0.6 nm and, then, decreased with increasing t Ru .…”

“…18 A SyAF layer consisting of a upper SyAF layer, a Ru spacer layer, and a lower SyAF layer, which are antiferro-magnetically coupled, is shown in the left box of Figure 1. [19][20][21] The Ru spacer-thickness strongly affects J ex for ensuring the read/write operation of the p-STT MRAM.…”

Dependency of Tunneling-Magnetoresistance Ratio on Nanoscale Spacer Thickness and Material for Double MgO Based Perpendicular-Magnetic-Tunneling-Junction

“…2a–f: a Co 2 Fe 6 B 2 free layer ferro-coupled with the upper Co 2 Fe 6 B 2 free layer via the Ta or W spacer ( i ), a Co 2 Fe 6 B 2 pinned layer ( ii ), an upper SyAF layer ( iii ), and a lower SyAF layer ( iv ); the lengths of boxes and vectors in the figure correspond to the magnitude of the magnetic moment and spin-electron direction for a magnetic layer. Initially, the Co 2 Fe 6 B 2 pinned layer ( ii ) was ferro-coupled with the upper SyAF layer ( iii ), while the upper SyAF layer ( iii ) was anti-ferro-coupled with the lower SyAF layer ( iv )151819. The SyAF layer in a p-MTJ spin-valve is essentially necessary to fixing the electron-spin-direction of the Co 2 Fe 6 B 2 pinned layer by ferro-coupling with the lower SyAF layer.…”
