    摘要: Magnetic tunnel junctions having a specular insulative spacer are disclosed. The magnetic tunnel junction includes a free magnetic layer, a reference magnetic layer, an electrically insulating and non-magnetic tunneling barrier layer separating the free magnetic layer from the reference magnetic layer, and an electrically insulating and electronically reflective layer positioned to reflect at least a portion of electrons back into the free magnetic layer.

    摘要: In certain embodiments, a tunneling magneto-resistive (TMR) sensor includes a sensor stack positioned between a seed layer and a cap layer. The seed layer includes a first buffer layer that includes a non-magnetic nickel alloy.In certain embodiments, a sensor stack includes a top and bottom shield and a seed layer positioned adjacent to the bottom shield. The seed layer has a first buffer layer that includes a nickel alloy.
