Cover Story: Utilizing a large perpendicular EB field as pinned layers has been the subject of intense attraction because of its potential in spintronic applications. However, typical AFM/FM systems indicate a limitation in attaining large EB fields (usually below 1 KOe). Thus, it seems that these cannot provide reasonable necessities for future spintronic applications. This experimental study shows that by replacing the commonly used AFM pinned layer with the ferrimagnet pinning layer, large PEE is generated by varying the Tb content of the Tb–Co layer. The developed FIM/FM films with great PEE show possibilities for pinned layers in spintronics and memory device applications. View this paper
