Abstract:
1. A spin valve structure in a spintronics device comprising a free layer, a synthetic anti-parallel (SyAP) pinned layer having an inner AP1 layer that is anti-parallel pinned with an outer AP2 layer through a coupling layer in an AP2/coupling/AP1 configuration, and a spacer or tunnel barrier layer formed between the AP1 layer and free layer wherein one or both of said AP1 layer and free layer are comprised of a laminated Heusler alloy with a configuration represented by [HA/IL] n HA where n is an integer ≧1 HA is a Heusler alloy layer, and IL is a metal insertion layer comprised of Al, Sn, Ga, Sb, Cr, or Fe x Co (100-x) wherein x is from 10 to 100 atomic %.
