Abstract: 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.
