Abstract
The thermal stability and high-frequency permeability of high-B-s CoNiFe th in films were investigated, CoNiFe films exhibited excellent soft magnetic properties and good thermal stability up to 350 degrees C, Annealing in lon gitudinal magnetic field enabled to achieve H-k as high as 35 Oe, while the H-k value after annealing in a transverse magnetic field was less than 20 Oe, By suppressing the core loss, the effective permeability of high-B-s Co NiFe thin film at high frequencies was improved successfully.
