Abstract :
In this paper, we have demonstrated a new type of synthetic antiferromagnet based spin valves comprising CoFe/CoFe/Ro/CoFe pinned structures exhibits many advantages such as much larger H/sub ex.eff/ as well as better bias control over conventional synthetic antiferromagnet based spin valves.
