Abstract
Memory devices and methods of forming the same include forming a memory stack over a bottom electrode. The memory stack has a free magnetic layer formed on the tunnel barrier layer. A first boron-segregating layer is formed directly on the free magnetic layer. An anneal is performed to cause boron to leave the free magnetic layer at an interface with the first boron-segregating layer. A top electrode is formed over the memory stack.
