Patent ID: 8508006

Claim:
A magnetic element, comprising: (a) a seed layer comprising one or more of Hf, NiCr, and NiFeCr 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 Co or CoFe, A2 is a metal or alloy selected from X, CoX, and FeX where X is one of V, Rh, Ir, Os, Ru, Au, Cr, Mo, Cu, Ti, Re, Mg, and Si, CoX is a disordered 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.
