ABSTRACT:
A magnetic structure for use in a perpendicular magnetic write head that prevents magnetic domain formation and reduces magnetic remanence in the structure. The magnetic structure includes magnetic layers sandwiched between thin non-magnetic layers. Each of the magnetic layers includes a relatively thicker layer of CoFe sandwiched between relatively thinner layers of NiFe.
