The thermal stability and high-frequency permeability of high-Bs CoNiFe thin films were investigated. CoNiFe films exhibited excellent soft magnetic properties and good thermal stability up to 350°C. Annealing in longitudinal magnetic field enabled to achieve Hk as high as 35 Oe, while the Hk value after annealing in a transverse magnetic field was less than 20 Oe. By suppressing the core loss, the effective permeability of high-Bs CoNiFe thin film at high frequencies was improved successfully.
