The stabilizing layered structure includes an antiferromagnetic layer, a first ferromagnetic layer adjacent the antiferromagnetic layer, a second ferromagnetic layer, and an antiparallel coupling layer between the ferromagnetic layers. The antiferromagnetic layer pins a magnetization direction in the first ferromagnetic layer along an antiferromagnetic polarized direction of the antiferromagnetic layer. A magnetization direction in the second ferromagnetic layer is opposite the magnetization direction in the first ferromagnetic layer. Each transducer also includes spacers on opposite sides of the sensor, at least one of the spacers being positioned between the sensor and the stabilizing layered structure. At least one of the spacers includes an electrically conductive ceramic layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tunnel magnetoresistive sensor having stabilized magnetic shield and dielectric gap sensor","description":"One general embodiment includes an array of magnetic transducers each having: a current-perpendicular-to-plane sensor, magnetic shields on opposite sides of the sensor, and a stabilizing layered struc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9818435","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.
