S. Mizutani et al., High-frequency permeability and thermal stability of electrodeposited high-B-s CoNiFe thin films, IEEE MAGNET, 36(5), 2000, pp. 2539-2541
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.
