Also included is a method for biasing a free layer in a reader stack by providing an exchange coupling between the free layer and a top synthetic antiferromagnetic (SAF) layer using a layer having RKKY coupling property positioned between the free layer and the top SAF layer and a magnetic capping layer between the SAF layer and the layer having RKKY coupling property."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensor stack structure with RKKY coupling layer between free layer and capping layer","description":"A reader stack, such as for a magnetic storage device, the stack having a top synthetic antiferromagnetic (SAF) layer, a magnetic capping layer adjacent to the top SAF layer, an RKKY coupling layer ad","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9633679","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
