The exchange coupling film includes an antiferromagnetic layer and a pinned magnetic layer including a ferromagnetic layer, the antiferromagnetic layer and the pinned magnetic layer being stacked together. The antiferromagnetic layer has a structure including a PtCr layer, a PtMn layer, and an IrMn layer stacked in this order. The IrMn layer is in contact with the pinned magnetic layer. The thickness of the PtMn layer is 12 Å or more, and the thickness of the IrMn layer is 6 Å. The sum of the thickness of the PtMn layer and the thickness of the IrMn layer is 20 Å or more."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Exchange coupling film, magnetoresistance effect element film using the exchange coupling film, and magnetic detector using the exchange coupling film","description":"An exchange coupling film in which a magnetic field (Hex) at which the magnetization direction of a pinned magnetic layer is reversed is high, in which stability under high-temperature conditions is h","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11476414","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.
