Patent ID: 8541855

Claim:
A magnetic element, comprising: (a) a seed layer that is one of Hf, NiCr, NiFeCr, Hf/NiCr, Hf/NiFeCr, NiCr/Hf, or NiFeCr/Hf that enhances perpendicular magnetic anisotropy (PMA) in an overlying laminated layer; and (b) the laminated layer having intrinsic PMA and comprising a multilayer stack of two metals, a metal and alloy, or two alloys represented by (A1/A2) n where A1 is a first metal or alloy, A2 is a second metal or alloy, and n is the number of laminates in the stack, the laminated layer contacts a top surface of the seed layer, or the laminated layer has an (A1/C/A2) configuration where C is a non-magnetic spacer.
