Abstract
A magnetic memory structure is provided. The magnetic memory structure includes a magnetic tunneling junction (MTJ) layer and a heavy-metal layer. The MTJ layer includes a pinned-layer, a barrier-layer formed under the pinned-layer and a free-layer formed under the barrier-layer. The heavy-metal layer is formed under the free-layer. The barrier-layer has a first upper surface, the pinned-layer has a lower surface, and area of the first upper surface is larger than area of the lower surface.
