The method includes providing a pole, providing a side gap, providing coil(s) for energizing the pole and providing side shield(s). A portion of the pole resides at the MFS. The side gap is between the pole and the side shield(s). The side shield(s) have a gradient in a saturation magnetization such that the saturation magnetization increases in a yoke direction perpendicular to the MFS. The step of providing the side shield(s) further includes providing a nonmagnetic structure having a side surface parallel to the MFS and providing at least one side shield layer. A portion of the side shield layer(s) are on the side surface. The portion of the side shield layer(s) has the gradient in the saturation magnetization. At least part of the side shield being formed by the portion of the side shield layer(s)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for fabricating a magnetic writer having a gradient in saturation magnetization of the shields","description":"A method provides a magnetic transducer having a media-facing surface (MFS).
