The FeCoNiM composition can be formed via an electroplating process by adding Fe2+, Co2+, Ni2+ and a transition metal salt to an aqueous solution comprised of other additives in an electroplating cell that has an Ni or Co as the anode. The plated HD magnetic material as the trailing shield in a PMR writer can minimize a wide area track erasure (WATE). Further, a high moment high damping shield can lower bit error rate (BER) and increase aerial density capability (ADC) of the write head."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electroplating of high damping material for trailing shield in a perpendicular magnetic recording writer","description":"The present embodiments relate to a PMR write head with a trailing shield that comprises a FeCoNiM composition.
