The magnetic layer structure is a layer of FePt-containing material, such as FePtCu, while the seedlayers and capping layers include layers of Cr, CrTi, Fe, FeCo or FeCoMo. These combinations enable the promotion of the L10 phase of the FePt-containing material which provides a high coercivity magnetic layer structure at much lower annealing temperatures than in the prior art."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fabrication of a coercivity hard bias using FePt containing film","description":"The free layer of a CPP-TMR sensor is biased by laterally disposed hard bias (HB) layers that include a seedlayer structure, a magnetic layer structure of high coercivity material and a capping layer ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493694","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.
